1 2014: 2 It's tradition to start the previous year's MLS Cup winner at No. 1 in the Power Rankings, but several members of the committee (including and especially the one writing this blurb) actually have LA outside the top five. They lost half their midfield, for God's sake. Head Coach: B ruce Arena

ruce Arena Key Additions: None (yet)

None (yet) Key Losses: Landon Donovan (M), Marcelo Sarvas (M)

Landon Donovan (M), Marcelo Sarvas (M) This Week: Friday vs. Chicago (10 pm; Unimas)

2 2014: 4 Deserve a top spot, and are probably one of the top three teams if you look at the course of the season. But for Week 1, with no Jermaine Jones and Andrew Farrell still learning a (crucial) new spot? The blurb-writer is getting antsy. Head Coach: Jay Heaps

Jay Heaps Key Additions: Juan Agudelo (F)

Juan Agudelo (F) Key Losses: Patrick Mullins (F), AJ Soares (D)

Patrick Mullins (F), AJ Soares (D) This Week: Sunday at Seattle (9:30 pm; Fox Sports 1/Fox Deportes)

3 2014: 1 Reconfigured half of the back line, and have no Ozzie Alonso to cover the entire midfield for at least a little bit. Like LA and New England, this team is built for the long haul, but don't expect the first several weeks of the season to be overly kind. Head Coach: Sigi Schmid

Sigi Schmid Key Additions: Tyrone Mears (D), Andres Correa (D)

Tyrone Mears (D), Andres Correa (D) Key Losses: DeAndre Yedlin (D), Djimi Traore (D)

DeAndre Yedlin (D), Djimi Traore (D) This Week: Sunday vs. New England (9:30 pm; Fox Sports 1/Fox Deportes)

4 2014: 6 This is the team everybody should bet upon getting out of the gates quickly. They return the vast majority of their roster and made a clear upgrade at center forward with the addition of Kei Kamara. Continuity, talent, and a little bit more savvy... watch out for Columbus. Head Coach: Gregg Berhalter

Gregg Berhalter Key Additions: Kei Kamara (F), Kristinn Steindorsson (M)

Kei Kamara (F), Kristinn Steindorsson (M) Key Losses: Bernardo Anor (M), Jairo Arrieta (F)

Bernardo Anor (M), Jairo Arrieta (F) This Week: Saturday at Houston (8:30 pm; MLS LIVE)

5 2014: 8 Watch out for Vancouver, too. The 'Caps were a goal-scorer away from being truly lethal last season, so they went out and spent on Rivero (who's generated lots of preseason buzz). That back line, however, needs to come together quickly. Head Coach: Carl Robinson

Carl Robinson Key Additions: Octavio Rivero (F), Diego Rodriguez (D)

Octavio Rivero (F), Diego Rodriguez (D) Key Losses: Sebastian Fernandez (M), Andy O'Brien (D)

Sebastian Fernandez (M), Andy O'Brien (D) This Week: Saturday vs. Toronto FC (6 pm; MLS LIVE)

6 2014: 7 One insane member of the Power Rankings Politburo had Dallas seventeenth in his preseason Power Rankings, which dragged them out of a top four spot. He has been sent to Siberia for re-education. FCD, if they stay healthy, are Shield & Cup contenders. Head Coach: Oscar Pareja

Oscar Pareja Key Additions: Michael Barrios (M), Dan Kennedy (GK)

Andres Escobar (M), Raul Fernandez (GK) This Week: Saturday vs. San Jose (8:30 pm; MLS LIVE)

7 2014: 16 We're much higher on TFC at this point than we were in 2014, when we had them 14th in the first Power Rankings of the year. The midfield and attack both have talent and depth; how well the defense functions should determine this team's ceiling. Head Coach: Greg Vanney

Greg Vanney Key Additions: Jozy Altidore (F), Sebastian Giovinco (F)

Jozy Altidore (F), Sebastian Giovinco (F) Key Losses: Gilberto (F), Doneil Henry (D)

Gilberto (F), Doneil Henry (D) This Week: Saturday at Vancouver (6 pm; MLS LIVE)

8 2014: 10 Another team that did major back-line surgery, and are still waiting for (underrated, extremely important) right back Chance Myers to get 100 percent fit. The attack should be among the league's best, though – with or without Rafael Van der Vaart. Head Coach: Peter Vermes

Peter Vermes Key Additions: Roger Espinoza (M), Krisztian Nemeth (F)

10 2014: 3 We had our doubts even before they were thrashed in Costa Rica. Bill Hamid was monstrous last year, and D.C. have to figure out how to reduce his workload. Dragging a third central midfielder into the game every now and then could help dampen the tempo and make this team more selective. Head Coach: Ben Olsen

Ben Olsen Key Additions: Markus Halsti (M), Michael Farfan (M)

Lewis Neal (M), Jeff Parke (D) This Week: Saturday vs. Montreal (3 pm; MLS LIVE)

12 2014: N/A This seems unrealistically high for an expansion team – even one that has Kaka. OCSC's defense is particularly worrying, especially given the fact that they want to play fast, open, attacking soccer. Head Coach: Adrian Heath

Adrian Heath Key Additions: Whole Team

None This Week: Sunday vs. NYCFC (5 pm; ESPN2/WatchESPN/ESPN Deportes)

13 2014: N/A Just as many questions as OCSC, even if they're a solid bet to play a drastically different style. What formation, though, remains a mystery – especially with several guys looking out of their depth in trying to replicate the Kyle Beckerman role during NYCFC's preseason flirtations with a midfield diamond. Head Coach: Jason Kreis

Jason Kreis Key Additions: Whole Team

None This Week: Sunday at Orlando City (5 pm; ESPN2/WatchESPN/ESPN Deportes)

14 2014: 15 Another team shrouded in mystery, thanks to the arrival of the new manager. Nobody's really sure what formation they'll play (though the 4-5-1 with Boniek advanced has looked promising), nor how reliable the midfield depth is. Head Coach: Owen Coyle

Owen Coyle Key Additions: Raul Rodriguez (D), Cubo Torres (F)

Raul Rodriguez (D), Cubo Torres (F) Key Losses: Tally Hall (GK)

Tally Hall (GK) This Week: Saturday vs. Columbus (8:30 pm; MLS LIVE)

15 2014: 11 It's not great when "decimated by injuries" is the first participial phrase in any season preview. Portland have a lot of guys, front to back, who can do good work in this league, but the best of them are starting the season on the sidelines. Add in a newly constructed backline and a new 'keeper, and there are just too many questions. Head Coach: Caleb Porter

Caleb Porter Key Additions: Nat Borchers (D), Adam Kwarasey (GK)

Donovan Ricketts (GK), Michael Harrington (D) This Week: Saturday vs. Real Salt Lake (10:30 pm; MLS LIVE)

16 2014: 13 One anonymous Eastern Conference rival warned us not to sleep on Montreal. And then they beat Pachuca. So let's consider this team No. 16 with a bullet – especially if Jack McInerney can rediscover his scoring touch. Head Coach: Frank Klopas

Frank Klopas Key Additions: Marco Donadel (M), Laurent Ciman (D)

Marco Donadel (M), Laurent Ciman (D) Key Losses: Marco Di Vaio (F), Felipe (M)

Marco Di Vaio (F), Felipe (M) This Week: Saturday at D.C. United (3 pm; MLS LIVE)

17 2014: 12 This team is a lot like the Red Bulls in that, first and foremost, we love the five-man midfield. It's hard, however, to know exactly what to make of the back line, and the fact that there are still questions at goalkeeper is one of the league's best long-running gags. Head Coach: Jim Curtin

Jim Curtin Key Additions: Fernando Aristeguieta (F), Steven Vitoria (D)

Fernando Aristeguieta (F), Steven Vitoria (D) Key Losses: Amobi Okugo (M), Carlos Valdes (D)

Amobi Okugo (M), Carlos Valdes (D) This Week: Saturday vs. Colorado (4 pm; MLS LIVE)

18 2014: 14 Brought in a ton of new faces, will most likely play a new formation, reconfigured the back line, and Mike Magee's still hurt. Things could end up going very right for the Fire, but a lot of pieces have to come together in a very short amount of time. Head Coach: Frank Yallop

Frank Yallop Key Additions: David Accam (M), Shaun Maloney (M)

David Accam (M), Shaun Maloney (M) Key Losses: Bakary Soumare (D), Gonzalo Segares (D)
