You can throw out the assessment of previous drafts when comparing college QB's today. The change in the college game from an era when the top teams relied almost solely on the run has passed and many college QB's throw the ball 10X more than previous era QB's.
Pro teams used to have to guess how good a college QB could be based on very little actual footage of a QB throwing the ball because they only did it occasionally. In today's game, college QB's pass the ball almost as often as a pro QB and come into the pro game far more advanced than their predecessors. This makes the transition from college ball to pro ball just that much easier. It is far easier today to get a full read on every aspect of a college QB's game because in the end, college QB's now find themselves facing many of the challenges of a pro QB.
I think the trend to 5 or 6 QB's being pro ready every year is here to stay and the success rate will be very high year after year.
The 2012 draft crop was 1st class and I have no doubt that the 2013 class will produce many NFL starters although I see no Luck or RG111 in the group, however there is great depth and as many as 3 or 4 QB's may well succeed and be 1st rounders before all is said and done.
Draftniks are just going to have to change their thinking on the potential of college QB's. The top 3 this year are Smith, Barkley and Glennon but the second tier is also bound to produce a starter or 2, so overall it will be a solid just not a spectacular draft year for QB's.
And proud of it!!!
