He's not Larry Brown - he's a journeyman NBA coach who hasn't been able to latch onto another gig.
I don't see this helping Tulane - it looks like one of those hires where you can't get at the in-demand younger coaches, so you opt for the used up old guy because you think you need a name at the press conference.
(Edit - the guy above referencing Hill at Fordham nailed it.)
I don't see how this can hurt Tulane either though, considering they are Tulane University. It's not like they have a high mountain to fall off of.
Yes, he was a journeyman coach in the NBA, but it's so rare to find an NBA team with the same coach for more than like 7 years. I think the Spurs are the only team currently?
Dunleavy was an NBA Coach of the Year at one point, and coached multiple teams for multiple years each. The man can coach. If this were a better program, then it would certainly be a head-scratcher.
