That could be viewed as luck, but could just as easily be interpreted that the rest of the team was swarming to the ball and was put in a position to succeed. Who knows. Maybe Baer is a hell of a DC at the MWC level, but his defenses just don't work at the P5 level.
That was something I really noticed when reviewing the highlights in the 'countdown' thread. The CU defense in the '90s did a much better of job of having 2 or 3 players at the tackle point, even when the initial solo tackle was successful. Swarming to the ball has many benefits in terms of follow through on tackles and making the most of fumbles.
I hope the new coaching staff gets some immediate results, but it's hard for me to believe that they can have that big an impact in only 20 some practices. I expect to see improvement by the end of the season though.
