Not trying to be a smart-***, but if there are tons of DJKs out there, I'd like to see examples. Examples of guys that put up his numbers in a college career that weren't drafted, invited to camp, signed as a FA, or signed to a CFL contract. If there are tons of them, then there should be an easy list to pick at least 10 of them out.
The point is, he had the talent, at minimum, to be brought in as a FA signing. The clubs are out NOTHING to do this, they see what he can do, if they don't like what they see. Bam. Cut. Done. No one did this (that we know of, maybe someone tried and DJK turned them down or he failed another drug test or something... we don't know). The point is there is a reason DJK isn't in the league, and it's because he lacked talent.
I'm not saying Ferentz is the reason, far from it. I'm just saying there has to be a reason DJK didn't get a whiff of the NFL, his talent notwithstanding.
