re: How would you rank coaches over the last 15 years?

I don't necessarily disagree with much of what you're saying, but the OP gave a specific time frame so I think it's a bit unfair to throw that to the wind. We're stricktly going by 2008-2022 according to OP. For Meyer that includes:

-An elite national title season at UF in 08
-A pathetic 5 loss team in his final year at UF
-A healthy tenure at OSU including 1 national title. 4-2 record in bowl games. 2 loss teams in 2 of his last 3 seasons.
-A top 3 finish in 2 of his 6 non-probation seasons

That's a solid resume that's highlighted by 2 natioanlt titles. But there is nothing about it that woudl put him in a tier of his own above kirby or dabo
