Then why don't we have one? There has been way too much turnover with our defensive coaches. Our defense has given up way too many points. My original question was is it lack of talent or poor coaching? You may not like it but coaches success is based on wins and losses while playing within the rules.
SCHEME (coaches):
I think it is tool early to judge the DC's scheming vs Louisville. Lamar puts us in a tight squeeze and small DEs aren't doing any favors.
I think the scheme vs Cal was probably fine, I liked the rush D and INTS, but I blame the players for that game. Our DEs aren't a huge strength, which puts pressure on the LBs and secondary. Corey Bell was bad and two young guys made youthful mistakes (Rene continuing a blitz, Dorn not being deep enough, etc).
DEVELOPMENT (coaches):
Carney has developed from a low-star linebacker into a surprisingly good third-down DE. Mikey Bart went from a low-star TE to a guy who is in the NFL (he wasn't fast, so technique and motor). Jalen looks improved though the interior opponents haven't been great.
Dorn has good technique on his tackles and his several break-ups. He looks great when he is in position. His being out of position is probably part youth, part Lamar (scheme or breakdown) and i'm guessing this improves.
TALENT (or lack of development blamed on coaches):
-Corey Bell started vs Cal but was benched vs LVille in favor of Sails. This says to me the coaches aren't in love with their secondary options. Rene came in RAW, some services thought he'd be a safety. The third CB, Sails or Bell are having trouble right now in multiple ways (plus they are skinny).
-Dominique Ross came in raw and needs to add weight before he sees PT.
-J Smith isn't very fast, good backup
-Former walk-on Holecomb looks a little less lost than last yr, but I wonder if he'd be a better strong safety.
-Not sure why Andre Smith is so much better than Cayson Collins, seems like instincts. Both were high 3*.
-Tomon Fox probably needs another yr in the weight room before starting.
-Drennon hasn't developed as much despite having the same three coaches as Bart. But his foot injury could've taken a toll. Powell is tbd.
Summary:
Secondary players are young, but they aren't rookies, so is their execution ability due to talent or coach - don't know but coaches are shuffling lineup. Coaches and player/talent are to blame for Cal. Not sure yet if we can blame coaches for Louisville.
