Goalkeepers

Jeff Attinella (South Florida) – One of the combine ‘keepers, Attinella was an All-American as a junior in 2009, but didn’t finish strong in his senior year.

Josh Ford (Connecticut) – The most athletic shot-stopper still available, Ford’s decision-making and distribution have kept him on the board.

Jimmy Maurer (South Carolina) – Member of the Chicago Fire PDL team and four-year starter at South Carolina, Maurer has an outside chance at making it at the next level.

Others: Clint Irwin (Elon), Zach Johnson (West Virginia)

Defenders

Michael Boxall (UC Santa Barbara) – The top defensive remaining prospect, questions about Boxall’s speed and ability on the ball pushed him out of the first three rounds.

Curtis Ushedo (UAB) – A monster at the back, Ushedo is an athletic centerback but didn’t show enough at the combine to warrant a SuperDraft pick. Look for either Toronto or Vancouver to pick up the Canadian prospect.

Greg King (Connecticut) – Australian left back who fared decently at the combine. Lacks size but gets can get forward and would improve depth at a shallow position. His international status hurts his attractiveness to clubs.

Andrew Welker (Seton Hall) – Versatile player who spent time as a forward and defender at Seton Hall. A bit undersized to be an MLS centerback, but has the soccer know-how to find a position and contribute.

Others: Indy Smith (UNC Wilmington), Ben Havey (Boston University), Mark Wiltse (South Carolina)

Midfielders

JC Banks (Green Bay-Wisconsin) – Son of former US international Jimmy Banks, JC is a playmaking midfielder who is weighing offers in Sweden. Would provide creativity in the midfield.

Daniel Keat (Dartmouth) – A tenacious, ball-winning New Zealand youth international, Keat’s stock slipped at the combine due to injury and his international status.

Nathaniel Baako (William & Mary) – The creative force behind William & Mary’s successful 2010 campaign, Baako didn’t receive an invite to the combine. Questions about his size make him a higher risk.

Lebogang Pila (St. Peter’s) – An extremely raw central midfielder, Pila looked a bit off the pace at the combine. While his physical tools are impressive, the South African would need at least a year or two to develop in MLS.

Matheus Braga (Penn State) – Led the nation in assists in 2010, but is on the older side (24) for a player coming out of college.

Ashley McInnes (Tulsa) – One of the best attackers left on the board, McInnes can play either wide midfielder or up top as a forward.

Ben Sippola (Butler) – After a strong senior season with Butler, Sippola earned First Team All-American honors. Doubts linger about his ability to cut it in MLS as an undersized midfielder.

Others: Ernesto Carranza (Sacremento State), Matt Marcin (Providence), Doug Rodkey (Maryland)

Forwards

Amani Walker (UC Irvine) – A large, physically imposing forward who can slot in a target role.

Matt Eliason (Northwestern) – Moved to midfield his senior season though played as a forward at the combine. Speed is a liability when considering his MLS midfield prospects, and he’d likely have a better shot as a forward.

Steven Beattie (Northern Kentucky) – The Division II Player of the Year scored 77 goals in four years at Northern Kentucky. Given the chance, he could become a contributor in MLS. Would a team use an international slot on this Irishman?

Andy Adlard (Indiana) – Didn’t have the strong combine needed to push himself into SuperDraft conversation. Scored seven goals and dished out seven assists while playing alongside Will Bruin his senior year, and could succeed in the right system.

Others: Spenser Thompson (UC Irvine), Sverre Wegge Gundhus (St. John’s), Blake Brettschneider (South Carolina)
