In APF 2K8, none of the 3-step drops work very well, but the 5-step drops buy you tons of time compared to how fast the routes are run in the game (much faster than Madden).
I have had online games of APF 2K8 where guys pass the ball 40 - 50 times on me and I only get 1 to 2 sacks, despite the fact that I have multiple gold and silver defensive linemen going against their generic OL.
If you look at the ratings of generic OL in APF 2K8, they are basically the equivalent of a backup OL in NFL 2K5, with the exception of APF 2K8's OL having jacked up stamina:
Here's a comparison of an elite NFL 2K5 DE to a gold DE in APF 2K8:
However, these numbers don't take into account that generic OL in APF 2K8 also get their ratings boosted by leadership, in addition to having a huge stamina advantage.
We still don't know what affect leadership has on the generics' ratings.
