There is another thing that Esch does really well:
Sacrifice his body for the good of the team. He is more of a BWS than a basketball player but he does whatever it takes for the Mavs when he's on the floor. He sets good picks, he bodies up with the physical players, he hustles, and he is a hard worker.
And personally that grittiness that Esch displays (when Nellie saw him play well against Chicago he asked Esch "where ya been?"... and Esch responded, "down at the end of the bench coach."
is why I think he deserves maybe 5-10 minutes a game as a reserve in our lineup. Given the right amount of time, he will use his fouls knocking people around, and give us the hustle and toughness that we sorely lack from the center position.
