Lol you linked pff as a source who praised skoronski.
Guess who was ranked higher both years in the nfl by their metric?
And just from a statistical one, Charles Cross only gave up one more sack despite being on an island outside vs the nfls best edge rushers, skoronski gave up one less sack vs defensive tackles with blockers on both sides of him.
Terrible example if you're trying to make a case for sliding cross inside.
EDIT: btw, that extra sack cross gave up is despite the fact that the seahawks threw the ball 81 more times. Titans were 30th in pass attempts
