Frequent vistor, infrequent poster. I should start by saying I am a fan of RG3 in college and I think he will transition much like Vick with small amounts of success that gain year over year in the NFL. I do not think he will be a hot hand like Cam right out of college. I do think that anyone at QB (even Flynn) will/would be an upgrade.
That being said... What if Pierre Garcon is really a super genius. What if he caught wind that the Colts were going to pull a shocker at draft day and take RG3 and aside from the gobs of money we threw at him... he wanted to play with Luck. He is the only man in the NFL at this time that would have been bargaining with both teams that have a chance at the two best college prospects in awhile. The NFL never works like this but it is pretty cool to imagine what if.
If all else fails... maybe Garcon would work at QB... he is after all the smartest man in the world.
