Sorry if I sounded angry, I didn't mean to come across as such. Here are the edits that I did to the O-Lineman. I'm not sure which ones have what effect, but I know that I'm pleased with them.
Speed, Blocking, and Strength ratings from the earlier post.
Agility - Between 50 and 65
Composure - Between 60 and 99
Stamina - Between 70 and 80
Consistency - Between 60 and 99
Aggression is at 0 for now. This may be changed.
None of the other attributes affect the overall rating of the lineman, so I changed them all to 0 except for durability. That is between 65 and 99.
I'm not sure if you will be happy with the interaction between the o-line and d-line in my roster, but you can see when I upload it (probably about a week). I don't know how much the composure and consistency ratings change the way they play, but like I said before, this formula has worked to my satisfaction. As a matter of fact, one of the biggest concerns I've had with other roster sets is how much the consistency ratings are varied. For instance, if you have an o-lineman with a pass block rating of 90 and a consistency rating of 10 (which I've seen in some roster sets), it seems like that may be a reason why the player would miss a lot of blocks. Who knows? I am willing to take on a attribute editing project, kind of like the one on gamechewover.com, if people are willing to at least give ideas and possibly even help. If anybody is interested in this, give me a pm and we can start a new thread dedicated to testing attribute changes.
