Terps fan here, I come in peace.
It's been intriguing to me reading this thread and following the story about Edsall's possible return to UConn, because there seems to be very little grey area when it comes to people's opinions. Having said that, I figured I'd shed some light on why he ultimately failed at Maryland, as I've seen that question asked multiple times here.
First off, he was put into a tough situation. He was replacing a well-respected coach in Fridge and was offered the job because Fridge steamrolled then HC in-waiting James Franklin on the way out. So there were already some bad vibes around the program when he got there.
That said, he didn't do himself any favors from the jump. He immediately changed the culture and come off as kind of a hard ass in the process. He always talked about bringing in great "young men", but he never let them be themselves. No du-rags seems pretty harmless on the surface, but good luck enforcing that in PG County, Maryland.
Randy's biggest fail however, was alienating prominent local high schools and coaches. He made little effort to maintain positive relationships with schools like Dematha, and that ultimately bit him in the ass when recruiting. Had it not been for Mike Locksley (who basically brought in Diggs on his own), Edsall would have not lasted as long as he did. His classes were filled with low 3*s with crappy offer lists. It's impossible to gauge DJ Durkin just yet, but he is a full 180 in terms of creating relationships with local coaches, and it's already paying off in recruiting in a big way.
Lastly, he refused to take any of the blame when anything went wrong. Some of you have already linked some of the articles so I won't do it again, but he notoriously deflected blame, even onto his players at times. If you asked him at the time, he probably thought he did very little wrong.
I don't know a single person at MD who is upset that Edsall is gone, and many major donors ponied up big dollars to get rid of him. The leftover roster that he left for Durkin is downright embarrassing for a B1G program, and he undoubtedly set us back a few years.
None of this is any indication of what he would do if he returned to UConn, but figured I'd shed some light on the situation for y'all. Good luck in finding a new coach!
