A lot of people in the stands were scratching their heads on that play. I have to wonder if he didn't think the ball might have hit one of the Md players who was retreating for a return setup. Otherwise, it was pretty dumb.
I'm not defending our less-than-stellar special teams play, but that play isn't on the coach. I'll bet my house that any kid who ever played jr. high football was specifically told not to stop a punt that is rolling or bouncing in the correct direction. There are some things a college coach should never have to say to any player.
I hope TA re-evaluates the decision to hand all special teams over to one coach. I think st perform better under multiple coaches each responsible for only one or two units. During st practice time (which is usually limited) each unit gets direct instruction and evaluation from one coach. It's more efficient and it places accountability for st play on everyone. Each coach can make decisions about who can and cannot effectively contribute. Each coach can focus on one particular aspect of st in addition to regular duty.
I heard Dave Wonnstadt say that as a head coach he always liked to coach some special teams units. It gave him direct involvement with a particular group and helped him get to know second and third string players. He also noted that those guys did not want to screw up under the direct eye of the head coach. I thought that was pretty sound logic.
