This is a lazy post. You left out a couple of important details. One, UConn won the overall rebounding battle 29 to 26. Second, Temple's centers combined to rebound four shots - and zero offensively - in 35 minutes. I don't know how much data we need before we realize that, while Brimah is not a great rebounder, KO's schemes are not conducive to big men posting huge rebounding numbers. They're taught to cross off bodies and allow the wings and the guards to scoop up the loose change. Nobody, since KO's tenure began, has rebounded well at the center position (incidentally, the current version of Brimah might do so better than anyone). Hell, look at how Olander's rebounding rate went down, how Miller's rebounding rate plummeted, etc. It's part player, part system.
If we are going to gauge Brimah's progress statistically, however, how about noting the improvement of his defensive rebounding rate from 11.1% as a freshman to 17.2% as a senior. How about noting that he is averaging more than a full rebound above his previous career high? 9, 6, and 3 in conference play? Second highest rebounding rate on the team (less than a percentage point behind Facey)? Or does that just not fit the narrative?
He is what he is, a limited, situational player that hasn't played the game long enough to be more than that. Just don't cherry pick statistics to fuel your tired campaign.
