I'm not at all hopeful things will improve under Chiz. Even if new position coaches make DL & CBs better, we're still lining up a million yards off the ball - so much cushion. Losing three starters is certainly a big hit for any team, Vohasek, Noah Taylor and Des Evans wouldn't have made us worse, but i'm not sure they would've impacted the scoreboard and that is why I'm suspicious of the scheme as much as the softness issues.
Modern offenses have running qbs, hunh, rpos, spread concepts, option formations, and bend-don't-break just isn't going to cut it.
I'm not sure if we're trying to occupy blockers rather disrupt, but the result is 4th string QB's having career games and teams picking up 3rd & short or goal & short pretty easily. Sometimes we'll stone someone at goal-line or get a huge stop on third-down, but same happened when one of Bateman's gadgets hit home. Neither have been consistent though.
Top offenses we've played per FPI:
Wake 19
Duke 27
App St 39
Notre 44
Pitt 73
Ga State 83
NCSU 88
Mia 91
GT 96
UVA 105
We can talk about players returning, but it going to take several coaching coaches and a few huge Portal xfer names for me to to be hopeful that we stop being bottom-100 defensively.
