Mullin had a good run of production, but if he kept his peak value for longer (it was only a few years in the late 80s/early 90s), he might've been regarded higher. Afterwards he was still a decent player, but not an All-Star.

Another name I'd like to throw out there is Larry Nance. I've never really heard people talk about him, maybe since he was part of several Cleveland teams that got stomped by the Bulls. They seem like a footnote in history, but a lot of them were pretty stacked, with a prime Ron Harper, Brad Daugherty (who is also underrated, but mostly because his career was cut short), and Mark Price (most people don't realize just how good he was in the early 90s, strikes me as an early Steve Nash, with his shooting ability and passing skills, although his passing wasn't quite as spectacular). Not suggesting that any of these guys are HoF material or anything, but looking back on the old Cleveland rosters has made me come out impressed.

Anyway, Nance was an efficient scorer (career FG% is .546), a good defender, and a surprisingly slick passer for someone his size. He never really gave superstar production, but he produced at an All-Star level for about a decade.
