Thats because Baynes isn't De Colo (who plays virtually all of his minutes in garbabe time, thus the lowest amount of total minutes on the team)
Baynes has played meaningful minutes starting usually the second quarters of games. He does play in garbage time, but he hasn't even impressed there. When he has gotten opportunity (I.E the @ GSW game when Splitter, & Ayers both got off to bad starts, Baynes came in and played even worse and Pop never back to him)
Looking at 10 games for accurate statistics, instead of the 29 games he's appeared in.
A larger sample size is always a good thing. He simply hasn't been very good. Talk about cherry picking.
Even going with his D-league statistics, he average 4.9 fouls per 36 minute (27 mpg, 3.5 are his actual numbers) rebounding and fouls are generally the most translatable stats (regardless of league) He is a still a very good rebounder.
Though...
Per 36 minutes
1.5 asts, to 2.9 Turnovers
1.3 blks to 4.9 fouls
Offensively his game is only above average in the D-league.
Neither of them seem to be the option at backup center. I wouldn't be mad if he proved me wrong, I just don't expect very much.
