Having McDuffy and Sneed, not to mention the safeties and lb's they have, allows them to blitz and leave those guys on an island. Massive luxury. That plus they tackle well. SF's yac was negated in the SB by clean tackling and good schemes placing players in place. Prime example McDuffy biting on the play action, then recovering in time to tackle Kittle rigth after the catch resulting in a loss of yardage. Against any other team that's a 15 yard gain.
The holding penalty on 3rd was pretty much his only mistake.
Trent McDuffie Maybe was DMVP
Best DL in game. Yes I think he's better than Aaron Donald. But debateable. For sure.
