Loved it. Like Cheeseheads said, he was protecting Rodgers. That DT could've jumped on him from behind easily.
Next to that, it was a clean block. It really didn't occur that long after Rodgers slid down. At the moment that Rodgers got out of Driver's sight, he was still running. I wouldn't have called it, anyway.
Still, even if it was a tad bit late, good play.
EDIT: Just like Colledge, btw. It shows what the team does for eachother and that they're a team in the biggest sense of the word. Colledge just got his WR out of one big clusterf***.
A bit dirtier than Driver's play, but still, not something I'ld complain about.
