those stats are stats against the teams, not just against each other.
they are head to head stats.
I will give you one thing, CBS did not trust Baynes in the second half, last night, as it was face paced and he mainly plays against the other team real centers like Embiid and say Jonas Valančiūnas.
They are team stats in the games where the players play. That is why Embiid has nearly double the minutes, if they were actually head to head they would have the same minutes.
Baynes can only guard Jonas on the Raptors. He can't guard the smaller faster guys. This is what I've been saying all along and his substitution patterns actually reflect this. He is good for 10-15 minutes in the games with the faster centers, but he shouldn't be playing more than that. He just doesn't have the quickness to do it.
