To me it's kind of the snow ball effect. If Freeney can come in and he gets single blocking and that results in a ton of pressure and a few sacks other teams are going to have to account for him. When that happens now they will have to figure if they want to double team Freeney or Campbell. This creates more mismatches for the Cardinals. It also allows gap blitzes to become more effective especially if the offense has to look at double teaming both Campbell and Freeney. Once Oakafor comes back you add another decent pass rusher into the equation. Add in Rucker who has made his presence known and you now have an effective 4 man rush in Campbell, Freeney, Rucker, and Oakafor and if you add in Golden, this could create matchup problems for the other team's Oline or have them keep a TE or RB in to help out which means less receivers in our secondary. If opposing teams end up having to keep 6 in to block 5 then at most they have 4 receivers running against 6 DBs. I like those odds.
