McKenzie has had a knack for being clumsy throughout his career. He's hilarious, clearly a favorite class clown on the team, and easy to root for.
But he has played himself out of the starting position. I am floored that he wasn't benched yesterday.
Singletary did block the wrong gap on that play. Had a great game otherwise. I'm not sure of the argument you're responding to, but McKenzie made too many awful plays yesterday to hand wave it away as a fluke.
