Yes, character is definitely a valued trait in the NFL these days.
But,as they said, another reason is that Iowa plays a pro-style offense.
That allows scouts to evaluate o-linemen,tight ends,rbs and qbs much better.
Read an article in yesterdays Chi.Tribune about Bears 6th round qb pick,dan lafevour,who never has taken a snap from center in competition while in HS and college. The scouts talked about how tough it is to know about all these spread qbs in college in terms of translating to the pros. Like they said, they throw a ton of short passes,and often they are in a spread because of lacking a strong arm.
This is why Ricky will get a very strong look from the scouts next year...he will be a mature,high-character,highly developed pro-style qb....makes him an easy default pick as he is not likely to be a complete bust transitioning to the NFL.
