I think you've blacked out some of the memories since Cooper left. Marmie went 22-31-1.The fact is Herm stinks as a coach. ASU could hire literally just about anybody and get essentially the same results they have gotten with Herm. He has done pretty much the same as Graham, Erickson, and Koetter... all of whom were acknowledged underachievers here. The only difference being they didn't have some old pal as the AD covering for them.
Bruce Snyder had a decent winning percentage thanks to back to back years where we went 20-4 but he was a sleep inducing 38-41 over the other 7 seasons.
Dirk went 40-34 but we all know it wasn't just our record that got him fired.
Todd Graham started out great going 28-12 but closed out his ASU career with 3 seasons where he went 18-20.
Ignoring the 2-2 Covid season, Herm is 23-15 over his 3 years. That's not exactly impressive and the infractions detract from his legacy but 8 wins per season still shines compared to what we've seen the past three plus decades.
