It's not worth replying to a guy who uses Leaf as an example but I will anyways because obviously you're not educated enough to know anything about Leaf.
Leaf, Couch, McNabb, Young, Leinart, Harrington etc were never in the same discussion as Luck the prospect is and it's not even close. Luck is compared to two guys only-- Manning and Elway. Those are the only "sure thing" quarterback prospects that has ever been discussed.
The only idiots who even made a comparison between Manning and Leaf are the media, and you all clearly bought into the hype of Leaf that the media gave. But it was no debate, Manning was the guy, by far.
Saying "d'oh he can be da next Leaf gais, he can be da next Couch" just shows a few things: you never watched Luck play, you never watched those other guys you mentioned play, and you're not educated enough to make a good argument and only use that repeated crap to make yourself feel better about losing the best quarterback prospect in DECADES. Instead of trying to talk about Luck's weaknesses, all you guys can come up with is "HE CAN BE COUCH". Stupidity beyond belief.
There's a reason why there will be teams offering the Colts up to 3-4 years worth of first round draft picks to try to grab Luck, but the Colts will do the smart thing and not accept it, as they get set for another decade and a half of excellence.
No team would do this for your little Harringtons, Leafs, Couch, or anything. They only do this for the next sure thing that is Andrew Luck. A guy who calls his own plays, is a leader, is poised, has all the physical attributes you look for in a quarterback (speed, mobility, arm strength, accuracy), intelligence about as high as Manning is, can lead a team from behind, can win big games, and most important of all, he is very accountable for his own mistakes.
You guys keep making the Couch/Leaf comparisons all you want, but it just shows you know nothing, and that you're stupid. But you will see next year when the Colts are on top of their division again.
