I watched each Giants game, some live some on TV and unfortunately Fassel is just ONE of the team's problems.
The Special Teams errors early in the season happened because the team is not well coached and the Dallas mistake happened due to an assistant coach giving the kicker a different instruction than the one Fassel gave to him. If Fassel's orders were followed that game probably would have gone to the Giants. What head coach has assistant that gives different (albeit slightly different) instructions to players when asked to relay the play?
The guys quit on him. When Fassel did not take DIRECT action with regard to Tiki's fumbling problems he lost a few of the players. I'm not saying bench Tiki or make him Levens' backup BUT Tiki should have started a game or two on the bench for the first offensive series.
Bottom line, the guy is a VERY good coach. He served the franchise well. He DERSERVES another shot given what he did with the team prior to this year. However, he SHOULD be sent packing because he has lost the locker room and the players have made it clear that they will not play for him.
BTW, the other problems with the team are injuries, a young O-line, and Tiki's fumbling, two of those things the new coach may not have to deal with next year. As for Tiki, he fumbled too many times in too many KEY situations. Hopefully, he'll work on it although there was never an indication that he was trying to figure out a way to reduce the fumbles.
