Fire hydrants are nice, but interior push against passers is the need here. Height/weight specs tell us only so much, though bigger is usually better when it comes to these guys. That being the case, not all big boys play with the same power/push.
I wouldn't dare say a 330-lb. road block is a bad thing, because they have their place in a rotation. But I love a 295-pound who's quick off the ball and can generate a fair amount of face pressure per snap. Watching QBs routinely climb the pocket with little concern gets old.
Not that Aaron Donald will just fall out of the sky or anything. I just think a discussion about bulk vs. power is interesting because it isn't all the same. Then again, having all of one thing and none of the other isn't serving us well - if that makes sense
