Until he starts throwing picks and everyone reverts back to: "Sugar high Josh needs to stop playing hero ball".
My thoughts: the defense isn't going to be improved this year. Even the signing of Surtain isn't getting us back to where we were. Bring in serviceable replacements (see: Norman) and roll.
You will need the offense to score more to make up for the defense presumably giving up more points (hope i'm wrong). Beane needs to bring another piece in. Perhaps a top receiver to be a second. Issue is what assets do we have? I would look to Epinesa, Elam, and Shakir as trade bait. Picks as well.
This team will need to gut a bit and rebuild going into the second phase of Allen's career. We are definitely in a window right now and WON'T be in the upcoming few seasons imo because of that. Time to strike now.
