Oh Michael Johnson, what have we got ourselves into?

I'm going to be re-watching the game today, because I want to be sure of what I saw regarding Michael Johnson and his "effort" today.  First, I routinely saw Johnson get rotated out for Larry English in 3rd down/pass-rush situations.  When he was in, he was loafing.  I saw no real effort out of the guy.  He's either ca$hed it in or still not completely healthy.  Either way, the best bet for the Bucs, if this type of "effort" continues, is a trade.  His cap penalties for cutting the guy are pretty rough.  Either way, it has taken this guy 8 weeks to start seeing his reps disappear and for him to start pouting/loafing.  People can complain about guys not producing, but, this might have been the worst investment this off-season.
