Special Teams is not an F-.
Kenneth Almanders as you stated is perfect on the season and hit 16 straight, he pulls the average up.
Thomas Leo as a punter has done a fine job, not great, but fine. He is averaging 43 yards per punt, I think he is doing a pretty good job.
Zylan Perry has done a good job returning kicks for the Cajuns averaging right at 25.4 yards per kickoff return.
Those 3 are doing their part to raise the average. Where UL has struggled is punt return, not that Jacob Bernard does a poor job when he catches the ball, when he does that, he has been about a B or B+, but 3 fumbles in 4 games is unacceptable.
Kickoff return coverage, I think has been pretty good overall, with a few breakdowns.
Punt coverage needs a ton of work.
and finally, kickoffs cannot go out of bounds as often as they have, that too is unacceptable.
Overall, I give UL Special Teams a C, the top 3 get an A and the bottom 3 get an F.
