It isn't emotional. He's just not good enough to make an NFL roster. Period. He's not that kind of talent. Jamarr Johnson was that kind of talent in the secondary. He made it for a year I believe.
He's "good" at Indiana. The dudes in the NFL are better. The dudes making a roster are better. Better talent is pretty consistently getting waived from NFL rosters.
Got ole Walty who couldn't coach his way out of a ripped paper bag at UMass and Hiller who couldn't coach his way out of a paper bag even though the paper bag doesn't even exist... That's who runs our offense... That kind of trash.
