Not really, there are a couple of differences.
1. Bell had no intention of playing that year. He wasn't in camp, he was in strip clubs and riding jet skis. I've said many times before that he knew he was injured a lot and didn't want to get hurt in his FA year. He and his agent found a loophole in the rules and he simply sat out, which I think was the plan all along. I refer you to former Steeler Mike Wallace about ten years ago who played like **** in his FA year because he was playing with one goal in mind which was to not get hurt and jeapordize a big FA contract. Mike wasn't taking any chances and putting himself out there for nobody and and if that pass sailed past him, well that's just the breaks.
2. Watt is at least in camp so it appears he intends to play. Watt IS under contract and it's time he gets his butt on the field.
