In recent vintage, ACC OL play - despite having several OL drafted very high and playing in the NFL, as a group, has been pretty bad, especially at the mid-tier and below.
Last year, 6 teams in the ACC ranked T-100 or worse in sacks allowed. 8 teams ranked T-90th or worse in sacks allowed. Even Clemson is in the 70s. Florida State jumped up from the mid to the upperclass of the conference in part because they got their **** together on the OL...they were 30th in sacks allowed. Last year, seven teams were in the bottom half of the nation in TFL allowed. ACC OL play simply put, ******* stinks despite putting 11 Day 1 or Day 2 picks in the NFL over the past 5 drafts, including many others on Day 3 that have started in the NFL and did so pretty early. Its a weird conference.
Offensive Line improvement is the single fastest way to go from the bottom or mid-tier of the conference to the upperclass. If Miami has their **** together on the OL, should be a good year. That will require us to avoid the injury bug, too...last year, we had an insane number of games lost on the OL and it doesn't matter what kind of team you've got around that offensive line, you're going to suck when you're trotting out 3rd and 4th string underclass linemen out there, nevermind if those 3rd/4th string players may not be P5 quality players at that point.
