I'll chime in again, No, I don't think has a very good chance of happening at all, regardless of his contract, retirement, quit if traded statements.
I think he'd be an immediate impact player on this offense if he was signed on saturday and played on Sunday. This guy plays with an edge and has his entire career. I don't think he'd be anything but an asset at this point in his career. Yes I like Jones, a lot. Yes I like Cobb a lot, I think adams has potential, but he's also shown he's not there yet either. Plenty of miscommunications with Rodgers, i think that will change, but it hasn't yet and so far this year he has yet to really get on the field. Smith may not be Nelson, but he creates explosive plays, still at this stage. It's rare for someone to out compete him to make a play. I don't see how that would be bad on this team. I don't think Janis or Abbrederis are even going to sniff the level that Smith is at right now, so while I'd like to see them contribute more, I'd gladly take what Smith could offer right now.
I also think he's serious when he says he'd just quit if traded. I'd like to think this team is attractive enough to get him to reconsider if it was something they wanted to explore, but he seems like a guy that wants to play with "his" team. He doesn't want to go thru assimilating to a new locker room, a new city, a new team just to win a ring. He wants to do it with they guys he knows and trusts, you know, his teammates, or not at all. again, not a bad quality to have in a player.
