Kubiak would be legally insane to not pick Grimes back up.
I know a lot of you think the position would be log-jammed, but I don't care. If we lost Foster or Tate, we'd be screwed in terms of depth. I had Forsett and Grimes as basically the same guy in preseason, so it's not like we'd be trying to see if Grimes can hack it. He can. Now he's available. Go get him, and waive a guy like Alan Ball who will be available any day of the week on the street if needed...Grimes played special teams in the preseason, and he's more valuable than Ball if Tate's injury lingers.
