the problem with your tall big men being out near the arc is post prescense and rebounding. that's why he was a wasted space. he was useless under the rim. Perry big out on the arc is bad for rebounding. We got crushed in rebounding in games when Holman played a lot last year because we rarely had a post presence.
Stats time.
Holman pulled down 2.1 offensive rebounds per game last season in 24.4mpg.
Perry pulled down 2.6 offensive rebounds per game last season in 23.9mpg.
Ado pulled down 1.7 offensive rebounds per game last season in 24.1mpg.
Your claim that a big man outside on offense is bad for rebounding just doesnt make sense here. All 3 played the same minutes per game, and Holman was hardly wasted space. Holman averaged half an offensive rebound less per game than Perry and about half an offensive rebound per game more than Ado.
Compare Holman's offensive rebounds per 40minutes to Perry this season- Holman was 3.44/game and Perry is 3.87/game this season. Again- how is that 'getting crushed' in rebounding?
Remember- this is offensive rebounding since we are talking about Holman stretching the floor on offense due to being effective from deep.
Now on defense, Holman averaged 4 rebounds per game last season. Ado averaged 2.8! And this season Ado is averaging 3.3! So Holman averaged more defensive rebounds than Ado averaged or averages this season, and Holman had the highest 3pg% for impact players.
Again- hardly wasted space.
I get that numbers can be interpreted to support all sorts of wacky stuff, but come on now- this is actual data that directly refutes what you are claiming. Holman was never a rebounding stud, but he was hardly wasted space. He grabbed offensive rebounds at a solid rate and grabbed more rebounds on both offense and defense than Ado while playing the same amount per game.
