Personally, while interesting, I think it's irrelevant for the Chiefs to be considering a QB prospect this next draft.
Smith is a five year deal at minimum and they are going to see what they have in Bray, who has the tools, before they take a shot at another QB, IMO.
The two guys I really like are Chuckie Keeton of Utah State and Marcus Mariotta or Oregon. Both will be eligible (Keeton is a Junior and Mariotta is a red shirt sophomore), but both will likely return for another year - depending upon who declares after this next season.
I'm not sold on Bridgewater. I think he's instinctive, but he's got some mechanical flaws and his footwork in the pocket isn't very good. He's a project when he gets drafted IMO. Reminds me a lot of Mark Sanchez at the same level actually. He'll be overdrafted, forced to play because of it, and it will probably adversely affect his ability to grow into the position at the next level.
Personally, I'd think that most drafturbators would be pretty thrilled with the Tyler Bray signing this past off-season. Here's a guy with all the tools and he'll get a chance to really grow and work on his mechanicals under Reid and Smith. At least he's got a chance to become something here if they are will to put in the time with him as they did with Rogers at Green Bay.
