I don't get your argument. 50% of the QB's mentioned above were 1st round draft picks. So your solution is to draft a QB in the 1st round???? As much as I like RGIII, drafting him or any QB in the first round doesn't guarantee anything. It's basically a 50/50 coin flip as to whether he'll be successful. Yes, this is better odds then picking a QB in later rounds, but we will be investing multiple years in developing RGIII, so if he doesn't pan out we've wasted 3 to 4 years of developing a QB. Look at the Jets with Sanchez. He sucks, yet they still keep running him out there because of the investment they put into him. St. Louis has so much invested in Bradford, and if he sucks next year, then what? At least with McCoy, since we only used a 3rd rounder on him, it's OK to replace him after one year with better alternatives.
Hopefully RGIII will be on the right side of the coin and will make this argument moot.
