New England Patriots head coach Bill Belichick believes Los Angeles Rams star Aaron Donald is "pretty much unblockable".
The Patriots will face the Rams in the Super Bowl at Mercedes-Benz Stadium in Atlanta on February 3, and Donald is expected to be a major factor in the game.
Asked what impressed him about Donald, Belichick told reporters: "Everything. He's pretty much unblockable."
Donald, a five-time Pro Bowl player and the 2017 NFL Defensive Player of the Year, tallied 59 total tackles and a league-leading 20.5 sacks in 16 regular-season games in 2018. He also forced four fumbles.
Belichick also praised the Rams' defensive line as a whole as well as the team's veteran defensive coordinator Wade Phillips.
"They're really good," Belichick said. "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.
"They do a really good job. Wade always does. 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."
