Well, I think both. I guess if you put a gun to my head and forced me to pick one, I'd take the talent. That leaves a team susceptible to injuries though (just ask the Turds).
If you have upfront talent then they get off the field and your not so reliant on depth because your Defense isnt having to play 90 faucking snaps a game with 40 minutes worth of TOP.
Be interesting to see the stats on how many plays Cortez & Russell averaged in 88?
