He didn't lose the team, otherwise they'd have laid down the last couple of games. The biggest probs on the team have to do with a bad, over-rated core of vets that predates Coughlin, goes back to Fassel. It's only a continuation of it.
Best thing would be to get rid of problem personas like Shockey & Burris, coupled with the departure of Barber. Get good picks for them to be used towards weaknesses such as the secondary. The core of the team has to be remade, no matter who the coach is.With the firing of their offensive coordinator, a better coach has to be used to help Manning develop.
FYI Parcells inquired about becoming GM and was turned down-good.
