I think that the RB factor can easily be addressed by increasing the cpu tackling slider. If you've never tried to play with it maximized, you'll see what I mean. Plus, as far as the cpu RB's vs. you, see what kind of data you get for an entire season. I think you should adjust your own pursuit/tackle (human) slider based on the relative strength of your team.
As far as
PR/KR yardage, unfortunately, that's a function of the game. 2K4 did this much better imo, which is why I wanted to focus on that game. Replay any given punt or kick return and watch the blockers....or rather watch all the non-blockers. It doesn't even seem to matter if you would temporarily up the blocking slider just for that play......it just a shame.
At present, the QB's and DB's are tweaked for cutting down INT's. This again, is a slider/tweak combo issue which I still need to look into. I'm probably going to have to knock some additional things down with DB's and even LB's to minimize the INT's.....it's all a tough balance, but I believe I'm close.
As far as when rosters will be ready......I just need to have more time to look through depth charts and exactly how I want to make the changes. Some positions need to be changed as well. It's too bad you can't make roster/depth changes in the editor like you can with Finn's hockey editor....unless there's something in the latest version whereby you can and I missed it?
