Who made an excuse? Just pointing out history
Ollie had a program on the mountaintop and considered elite in the basketball world. To me his only job in the early part of his career, was to not see UConn descend to the ranks of irrelevance. Oh the others you mentioned jobs was to ascend their programs which gives them latitude and time (luxuries for a coach).
Programs on top
rarely never bring in rookies. Kansas, North Carolina, Kentucky, UCLA and other blue bloods didn't do that and they remain relevant. Even Texas went out and replaced Barnes with Smart, and Arizona went and got Miller both 'not settling'.
Sadly with declining post season NCAA appearances, middle of the pack conference ranking, no NBA player accessions, and mediocre season records we have descended so quickly that we are becoming a irrelevant and certainly less attractive to our fan base (empty seats) and national media.
Ollie does not have the time and latitude afforded the HOFer's you mentioned, because UConn is not looking to become an elite program but looking to remain one. Our Coach needs to prove he belongs, and that is done through winning games (a whole lot of them), conference domination and post season successes.
Anyway, I think Tom Izzo who had some assistant coaching experience and took over a well known and established Big Ten program as his 1st head coaching gig, is a better one to make Ollie comparisons to:

1998-99 Michigan State Big Ten 38 33-5 .868 NCAA Tournament; Reg. Season Champion; Conf. Tournament Champion; NCAA FF
1999-00 Michigan State Big Ten 39 32-7 .821 NCAA Tournament; Reg. Season Champion; Conf. Tournament Champion; NCAA FF; NCAA Champion
