These are final post-Bowl rankings and don't make any adjustment for the two years of forfeits. I also omitted 2016 as including it with Kelly 1.0 would make Kelly 2.0 look like a much better coach. The end conclusion is he has improved but is still not at the level needed.
The schedule appears to be slightly easier for Kelly 2.0 than Kelly 1.0 but 2.0 is playing slightly more top 10 and top 30 teams a year.
