I think that Luck and Tannehill have the stuff to have long successful careers. When you watch them read defenses, call audibles, make drops from under center, adjust protections, and stand tall in the pocket under pressure, you see why these guys were top ten picks. They've got the look and feel of a franchise quarterback.
While RG3 is winning games and producing, I'm just not too sure his style of play will have continued success. The read option is working right now, but eventually teams will key up on it and shut it down. Just look at what has happened to Cam Newton this season now that teams know how to gameplan for him.
Wilson has been impressive considering he was a later draft pick. While he's not putting up eye popping numbers, he's winning games. A lot can be said for that. I don't think he'll ever be elite, but he doesn't need. He has the tools to be a very good game manager.
Weeden looks like a bust on a bad football team. Maybe he'll figure it out in the next couple of years, but by that time he'll be over 30 and on the downturn physically. I'm very glad we didn't draft him.
I also have my doubts about Griffin long term. Let me see him beat defenses consistently for a few years while not getting knocked out and concussed.
That and the fact that he's really not running a true NFL offense. Shanahan has totally built that offense around him. It's very similar to what he ran at Baylor. It's a lot of shotgun and read option. Cam Newton did a lot of that in his first season, and he had a lot of success, but this year it's begun to catch up with him. I expect a similar result with RG3. He'll shock plenty of people this year, but slowly teams will learn how to shut him down. It's just like Tebow and the Wildcat, it tears you up for a year or so, but then defensive coordinators figure it out and it becomes worthless. There is a reason you don't see teams running offenses like that for long periods of time, it's because it cannot be sustained.
