Definitely! Breakouts by division, coaching changes, and all kinds of other historical secondary stuff would be super interesting to see on coach profiles.
A little off topic, but I'd also like the option of setting a recurring matchup with a coach. For instance, if I want to play against topdog's Coker team in the 5th non-con matchup every season, the system automatically keeps it in and alternates home/away every season (if he accepts the challenge, of course).
