Gold left with bad blood. The Poston's had convinced him an undersized LB with an ACL was worth a 15 million signing bonus.
He was basically given a one year offer with a pretty big (3.5) roster bonus that Tampa couldn't afford. He isn't a Sam anyway so he hit the market again.
One positive you have to remember is that Gold can now play Sam in a pinch, and he's got the ACL hopefully behind him. That knee injury really hurt his value, something that seemed obvious to everyone but the Postons. Every time those two enter my mind it reminds me of Bang's cartoon and the Soldier Winslow. God that was funny.
