Whatever you do, don't make fun of the beard of Garrick Sherman. CBS analyst Doug Gottlieb learned the hard way when he took a light-hearted jab at the Notre Dame center which resulted in a straight ethering by Sherman.

So, yeah, let this be a lesson to you. Don't make fun of Sherman's beard by any means necessary!
