The Strong side sets the edge for the Defense, it's pivotal to have a good SDE vs the run game.
JJack was our Strong side last year because we didn't have a natural SDE to replace Chad & it showed. JJack played out of position, he's not a Strong-side end he's a pure pass rusher, but Garvin played better as a Weak-side rusher.
If Hill is around the 250-260 range you definitely want him on the Strong side because Garvin is a pure assassin as WDE. If we have to play Garvin on the Strong side it won't stop him, but it will not be putting him in his best position to utilize his skills the most effectively.
Both Patchan & Rousseau are prototype Strong side rushers, but due to their wiry long armed frames they can also be Weak side rushers who do nothing but collapse the pocket & attack the QB.
We actually have 3 possibly 4 situational pass rushers who are difficult matchups bringing immense pressure on 3rd & longs with Garvin, Hill, Rousseau & Harvey. We can mix it up like crazy giving Offenses different looks.
