I'll concede your point about their regular season performance, I actually didn't realise so many of their losses were in conference, but you couldn't be more wrong about their lack of an inside presence:
Forward - #21 Bennett Davison, Jr. (9.7 ppg, 6.4 rpg)
Center - #42 A.J. Bramlett, So. (8.1 ppg, 6.9 rpg)
Let's see, that's 18 and 13 between the two of them, on average, all year.
By the way,
here are the starters and key reserves for that team. Interesting to note that Jason Terry came off the bench.
Bennett Davision and A.J. Bramlett were MAJOR contributors for that team in its run to the title. While neither was a big-time back-to-basket scorer, they were both agile, ran the floor well, played interior defense and could score off feeds from Jason Terry and Mike Bibby.
That was anything but a doughnut team.
