People were ranting and raving about having horrible special teams but are cavalier about cutting a core guy on every one of them as well as the punt protector. It's easy to say "just git sum yung hungry guys in there to hit sum one!" but guess what, it's not that easy.
Also, Kuhn IS their best blitz pick up guy, it's not close, and it hasn't been since Bjacks left. This is a team that had both Quinn Johnson and Vonta Leach on the team and cut them both; THEY DON'T WANT A BIG BATTERING RAM FULLBACK. They want a guy who can take the occasional carry, catch a few passes, make a few lead blocks and then pick up the blitz. They also need him to be good on special teams to free up other roster spots (Johnson, for example, could never find the field on special teams) and know the system.
2.3 mil sounds like a bit much, but the people who really understand what he contributes seems to think that's at least close to an acceptable number, so I'm not going to complain. Now, if he blows some assignments and stops giving hell on special teams, cut him right away. No question about it.
