Unless we keep getting 330 pound linemen who are nimble on their feet, we will continue to struggle vs mammoth nose tackles.
I think you're overstating this a little bit.
From what I've read for a few years now, actually the trend of Olinemen has been on the reversal.
An NFL Olineman averages around 310 nowadays, with the college guys just over 302.
The Ravens, for example (according to ProFootball Reference) had 3 guys at 309, 307, and 300.
They didn't have any problem against the Pats.
