When Belichick was asked during his media availability Tuesday what stands out about Donald - who's widely expected to win his second consecutive Defensive Player of the Year award - the Patriots coach left nothing open to interpretation.
"Everything. He's pretty much unblockable," Belichick said.
"Yeah, they're really good. They've got great inside power and quickness and they've got a great edge rush. They've got a lot of good players, a lot of guys that are hard to block. Yeah, they're good. They do a really good job. Wade (Phillips) always does (a really good job). He's an excellent coach and he does such a great job with all of those guys there. They have a variety of players and they're all a problem."
The Patriots' offensive line is arguably the best unit in the league, while Donald - who recorded a league-best 20.5 sacks during the regular season - and Suh have proven to be the best interior pairing in football this year. Whoever wins this matchup is likely to lift the Lombardi Trophy on Feb. 3.
