A lot of comments about players being kept for "emotional" reasons. I don't buy that. This is a business they are in and the business is winning. TT believes draft and develop is the best way to do that. The Packers consistently are one of the youngest teams in the NFL. That doesn't happen if you keep players just because you like them and can't let them go. It also makes sense to maintain a certain amount of leadership on the team, and I think that better explains why they keep some players - Hawk and Driver come to mind.
It should be noted that Hawk and Driver took significant pay cuts after 2012, neither under the guise of clearing cap space for competitive reasons. These were value-based cuts; neither was worth what they were contracted for. Had either player declined to take the cut it's a solid guess neither would have been back.
I think the closest one can get to an "emotional" roster decision was offering to cut Driver to a generous $2.5 mil from the contracted $5.0 mil since he was looking at little playing time. That appears to me to be more like calculated sentimentality than emotion.
Kuhn has value. Block, pass catch, dive, special teams...he does several things reasonably well. He would seem to be valuable for some intangibles; leadership on special teams where a lot of guys come in not wanting to do it.
As previously noted, he's lauded by insiders for his knowledge of the the offense. Without being inside the meeting rooms, on the sidelines or on the field, it is hard to know what his contributions may be in prep or in-game adjustments. However, the insiders would not make these comments if there was not some contribution.
