I am going to go as in depth on each of them as possible. Primarily because I am bored.
Luck- The first round draft choice. Therefore he is expected to be really good. He has turned the whole Colts team around. The Colts are headed to the playoffs. Luck has led a ton of 4th quarter comebacks. However he has thrown a bunch of picks. He does though have the record for most passing yards for a rookie. Primarily because his team is one dimensional.
RGIII- The second round pick. Therefore a lot has been expected of him. Had a rough start but they have been winning. He has hurt himself a few times but has rebounded and is still playing well. He is a duel threat because of his running ability. However, even though he can run he can still throw very well. Also RGIII has the fewest interceptions of the 3. That is a good stat to have.
Wilson- 3rd round draft pick. He earned his way to the position beating out Matt Flynn. He seems to be improving each week which is good. Also he has the ability to dodge defenders like no one else. Since the middle of the season he has had the best passer rating (or one of the best).
Ummm...ya. If Wilson keeps playing at the level he has in the past few weeks he really should win. Again, Luck just as too many interceptions for me to pick him.
