DeAngelo Williams is still very much angry about the way the Carolina Panthers released him.

The former Carolina running back spent the first nine years of his NFL career with the Panthers but was let go prior to the 2015 season. Eventually, Williams went to Pittsburgh, where he kept the pink slip his old team gave him in his locker as motivation.

Williams is currently a free agent and is hoping to play more football, but the Panthers are one of four teams he absolutely will not consider signing with, per a conversation with ESPN’s Adam Schefter on his podcast. Williams admitted it was all about his bitter breakup with Carolina’s front office:

The reason being is because of the way they handled my exit. I had no problem getting fired but the things that went on there that I didn’t like and I still don’t like to this day . . .

Schefter followed up and asked if he was on good terms with the team today, and Williams responded with this:

Well, no I wouldn’t say I’m on good terms with them today because we haven’t had a conversation since my release in terms of any apologies or anything of that nature, anyone talking to me from that front office to even rectify the situation with the issue that we had there, so there’s no point.

Williams also singled out the Cleveland Browns because they’ve never had a winning season in his lifetime and the Jacksonville Jaguars because the only cool things they ever had going for them are Fred Taylor and swimming pools in their stadium.

Finally, Williams said he would also never play for the Dallas Cowboys because he grew up a San Francisco 49ers fan in the 80s.
