Just look at the difference between Babcock and Keefe.
Sheldon Keefe in his post game. He said the special teams haven't been good all season, but were getting all sorts of luck. He then said "we as coaches need to do a better job preparing our team".
On an answer to his next question. He said we have dealt with significant injuries, but that shouldn't be an excuse. We have more then enough depth here, and a lot of good players. We as coaches need to be able to adjust. Special teams have been the difference in a lot of games, and that is large part a coaching issue.
He pretty much blamed himself for the team's play. Keefe is willing to take ownership for how the team performs. Babcock just gives out excuses.
