I'm cooling down to the idea of trading Fox for Simmons (not to mention the additional bounty we are expected to give up, which many agree on).
The issue is not talent. Simmons has clearly shown that he is an elite level talent, plays defense, and also helps balance our roster. So, in those terms alone, the trade would be a win for us.
However, given his attitude recently, I am scared that he will force our hand just like he is forcing Philly, driving his value further down. Do we, as an organization, ownership, and fan base, have the cojones displayed by Philly so far to fine him, refuse trade offers they consider unworthy, and let the drama drag out? And in the unlikely scenario that his mental health is an actual issue, what then?
Do we want the drama as long as he is around? Can a dysfunctional organization like ours handle it, while losing Fox, who in most aspects, has been a model citizen? I think the risk is far too high. If the contract length was couple of years at worst, fine, swing for the fences. This, I think, is too risky.
ps: In one aspect though, I think Philly's attitude will help the team that trades for him. They can follow the precedent set by Philly and say that they won't pay unless he suits up/cooperates. The challenge will be if he suits up, but goes through the motions, trying to force a trade. He has shown that he is unprofessional enough to behave like that.
