To be honest, I can't figure out why DG keeps setting the bar so high for McCown. I believe it's a motivational tactic, but I don't think it will work. What I saw from McCown in the QB Challenge actually solidifies my opinion that McCown will not be the starting QB for very long.
The drills themselves mean absolutely nothing, and McCown certainly showed well in the "athletic" events, but he certainly appeared to lacking in the maturity department as compared to Brunell and Trent Green, for example. I thought it was easy to spot that the various levels of maturity were directly proportional to age. Unfortunately, maturity is a big part of being an NFL QB. Nothing I saw suggests that McCown is not still going to be a "deer in the headlights".
The most impressive QB by far was Mark Brunell, and amongst 3 of the most accomplished receivers in the game, Boldin stuck out like a sore thumb. Those of you who think NFL people have any freakin clue what they are talking about when it comes to personnel should look at Boldin, whom every team passed on, including the Cards who wanted Bryant Johnson instead.
If Larry Fitzgerald is as good as they say, Boldin/Fitzgerald will be every bit as good as Carter/Moss.
