The Miami Dolphins and Indianapolis Colts are two undefeated teams trying to establish themselves in the AFC. Both have young quarterbacks with promise and solid second-year head coaches.

Indianapolis beat Miami last year, 23-20, in an exciting matchup in which quarterbacks Andrew Luck and Ryan Tannehill both played well.

But who will win this season’s matchup? ESPN.com Colts reporter Mike Wells and ESPN.com Dolphins reporter James Walker weigh in.

Wells: Sunday will come down to which quarterback from the Class of 2012 -- Luck or Tannehill -- can limit his mistakes. And I’m sure we’ll talk about them before we end this conversation, but before that, James, we have to address the Mike Wallace situation. It seems like Wallace was being selfish by making Sunday’s win over Cleveland all about him because he only had one catch. For a Dolphins team that’s had only one winning season since 2006, Sunday should have been about getting a nice road victory to open the season. Not about Wallace. I know Wallace cleared up his comments Monday, but it shouldn’t have gotten to that point. Is that a sign of things to come out of Wallace, the $60-million man?

Walker: The situation was not ideal, but I thought the Dolphins did a masterful job putting the Wallace issue to bed during the week. Miami’s coaches supported Wallace’s competitiveness and desire to make an impact. Wallace also clarified that he was more upset at himself, and I expect he will be extra motivated to have a big game. Speed kills in domes, and I don’t think there will be a faster player in Sunday’s game than Wallace. Look for Miami to find more creative ways to get him the football in the event the Colts consistently double Wallace, which was Cleveland’s strategy. Speaking of strategy, I was surprised to see how much Indianapolis struggled last week with the Oakland Raiders. The Colts trailed Oakland at home with less than 6 minutes left in the game. Was this first-game jitters and what needs to be fixed?

Wells: You weren’t the only one surprised. I think most people were, especially when you look back at the Colts’ first two offensive series. They scored with ease and all indications pointed to Luck having a special day after he started 11-of-11 with two touchdowns. But you have to give credit to Oakland quarterback Terrelle Pryor. He did an excellent job creating with his feet. He kept the Colts off balance and his team in the game until Luck became the hero. Tannehill is a more traditional quarterback. Luck, Robert Griffin III and Russell Wilson are the quarterbacks everybody talks about from 2012 -- and they should be talked about after they led their teams to the playoffs -- but do you get a sense down there in South Florida that Tannehill has the tools and work ethic to close gap on the three QBs I just mentioned?

Walker: I really like Tannehill’s tools, Mike. He can make all the throws, has good mobility and feet as a former college wide receiver, and he doesn’t get rattled often. Those are all qualities you want in a quarterback. He looks the part, but I still need to see him win consistently. What was interesting about last week’s win over Cleveland is Tannehill took over the game in the third and fourth quarters. Last year Tannehill played not to lose games. Last week Tannehill went out and won the game. That’s probably the biggest thing that separates Tannehill from Luck and other members you mentioned from the 2012 quarterback draft class. Tannehill can certainly learn from Luck and his fourth-quarter comebacks. Mike, where is Luck in his development in Year 2?

Wells: Everybody talks about sophomore slumps with players. You should go ahead and look elsewhere because that won’t be the case with Luck. He refuses to settle. The only thing he wants to talk about is getting better. That’s what you like to hear from your franchise player. Luck likely won’t pass for as many as yards this season because the Colts are putting an emphasis on the running game with Vick Ballard and Ahmad Bradshaw. Those two players should take a significant load off Luck’s shoulders. But it won’t be easy for Luck this weekend. Miami’s defense looked pretty good last week against the Browns. Six sacks and three interceptions. What makes the defense so dangerous?

Walker: The Dolphins focused in the offseason and training camp on forcing turnovers and pressuring the quarterback. The work clearly paid off with the stats you mentioned. But perhaps the most impressive stat is Miami hit Browns quarterback Brandon Weeden 16 times, which included the six sacks. The Dolphins’ front seven is both fast and physical. They have a deep rotation on the defensive line. For example, No. 3 overall pick Dion Jordan is a backup who only gets limited snaps. Dolphins defensive coordinator Kevin Coyle has done a good job and really likes the group he has. I think the best way for Miami to beat the Colts is the rattle Luck, force turnovers and try to make it a low-scoring game.
