OK, I've seen people complaining about their eyeballs exploding at some of the ratings, so I guess I better fill in some gaps here. First, let me re-iterate that the ratings are based on MY understanding of how stats are used, based on some conversation with oriole_fan. He has NEVER given me any "formulas" or game code, so I don't have an "inside track" on the engine. (If I had, my Texas team wouldn't have been 8-5 in beta.) The weights given to any stat are strictly mine.
SPEED - This is one of the stats I've had a hard time getting a handle on how much weight to put it, across all positions. I believe it to be a major factor in deep passes, a minor factor in medium passes, and "a" factor in running the ball, although I'm not certain how much. It was more problematic on defense. As far as DE go, I don't believe it's a factor at all, unless there is something in calculating whether a runner gets "around the corner" on outside runs. It's not used in determining pressure on the QB, as far as I can tell. I'm trying to confirm this with oriole. For LB in general, because the game uses just "inside" and "outside" (instead of "left, middle, right") for sides of field, the major place speed in real life would be used is somewhat negated. The DB complaint is ridiculous, since SPD is actually a higher factor in these ratings than my old ratings, and higher than the WIS default ratings used in the 3.0 beta.
TECH - other than QB, TECH gets reduced pretty much across the board in the new ratings. I was told that Tech is used as an overall modifier (like ATH was in the 1.0 engine) instead of a "check this attribute for success" kind of thing. I'm pretty sure that a change norbert made when he first started doing the new engine WAY back when. It's a pretty dramatic change.
I saw a question about Game Instinct for FB, and I agree, I need to make a change there. I'm thinking STR (-4), BLK (-2), ELU (-2), GI (+8).
Hands on LB was an oversight on my part. We'll subtract 1 from ATH, STR, TKL, and 2 from GI, and give HND +5
Hands on QB has never been a consideration. I don't think it's a factor in fumbles, and there's no other place it would be used for a QB.
I think that about covers it for now. Please ask questions if something doesn't look right.
