John Henson is basically Ed Davis except he's not.
Holler at me when Davis has the rim protection, shot blocking, and defensive rating numbers Henson had last season. I mean it's a joke to put the two in the same sentence.
Yeah, he blocks more shots, but about those Defensive Rating numbers before this year...
Henson: 105, 98, 108, 102
Davis: 104, 107, 103, 102, 101
Yeah, absolutely no comparison when it comes to overall defensive impact.
Of course, you might be right that these two guys can't really be compared:
Henson Offensive Rating: 108, 108, 106, 106, 103
Davis Offensive Rating: 115, 128, 124, 110, 114, 108
Davis' worst Offensive Rating (5 years ago) is equal to Henson's best.
Davis also blows Henson away in Defensive Rebound Rate, Offensive Rebound Rate and (unsurprisingly then) Total Rebound Rate.
Davis also has a significantly higher scoring efficiency.
By eye test, I thought they were fairly similarly valuable big men, in terms of being good defensive bigs who are both solid roll men on offense. But you encouraging me to look deeper at the stats has convinced me that, indeed, Ed Davis is much better overall. Good catch.
