More and more it feels to me like Portis will be the pick at 16 if the Celts stay there, although with Danny Ainge you can never rule out him selecting a score-first guard if Payne is available at that spot.
Not much choice but it may turn out well. Take Portis for themselves if he is there or take Payne/Grant for trade back with Rockets. Despite Portis' lack luster combine #s he is similar to Aldridge.
Aldridge vs Portis
Height:6'11 vs 6'10
Wingspan: 7'5 vs 7'2
Standing reach: 9'2 vs 9'1
Weight: 232 vs 246
B.Fat: 8.7 vs 8.9
No step vert: 27" vs 25"
Max Vert: 34" vs 32"
Max vert reach:12' vs 11'8
Agility: 12sec vs 11.7sec
Sprint: 3.47 vs 3.56
Both played 2 years of college ball
College final year
Aldridge 34mpg, 15pts, 56fg%, 65% FT, 10rebs, 2 blk
Portis 29mpg, 18pts, 53fg%, 73%FT, 9rebs, 1.2 blk
So Portis has more weight, better scorer, and more agile yet LA was taller and more explosive but not by much.
