It seems pretty clear that the Indianapolis Colts will have the 1st pick in the draft and if they decide to trade it, who will be trading up. I am now going to go over some different scenarios of teams trading up. Remember that its way to early to be sure, this is more to create some discussion and to see what everyone else thinks.
Team #1 - Cleveland Browns - Colt McCoy is a decent QB. He's one of those guys that can take you to the playoffs but won't win you a championship. Considering that they own the Atlanta Falcons first round pick gives them a golden opportunity to move up a significant bit. Also becuase they will probably get another Top-5 pick would give the Colts a opportunity to still get a star player.
Team #2 - San Fransisco 49'ers - Don't get me wrong, Alex Smith has to an extent revived his career however his play isn't why the Niners are 8-1. It's due to there run-game, great defense, and magnificent coaching. The Niners could trade up to get Luck because they have a player that many people tend to forget about, Colin Kapernick. Kaepernick was drafted as a future franchise QB, however packaging him with some picks would allow the Niners to select Andrew Luck.
Team #3 - Seattle Seahawks - The Seahawks probably won't have a high enough pick to select the #3 QB, Matt Barkely. If they aren't happy enough with Landry Jones or Robert Griffin they could trade up. The Seahawks are in rebuilding mode however have some decent recievers and a star QB would help the team greatly.
Team #4 - Washington Red
Deadskins - Same situation as with the Seahawks, they probably have won themselves out of competition for the Top 2 or maybe even Top 3 QB's. The QB situation here is dismal and anyone would help however if they dont like the other prospects enough they might try to trade up.
Remember these are just my opinions and they will change as the season progresses.
