Boley Levels Cowboys Season (4:47)

Michael Boley breaks down his devastating hit on Tony Romo (4:47)

Undrafted rookie fullback Chris Gronkowski's blown assignment resulted in a blitzer coming free and cracking Tony Romo's collarbone.

It's easy to second-guess the decision to keep Gronkowski and cut fourth-year fullback Deon Anderson.

It's also silly.

This is the second time in three seasons that Romo suffered a broken bone due to poor pass protection. He missed three games in 2008 when a Cardinals linebacker came free, sacking Romo and breaking the pinkie on his right hand.

Guess who missed that block? Deon Anderson.
