Yeah, obviously guys with a 30 or 37 overall rating won't have 100 for stuff. I'm guessing that there's something in your league causing some league averages to get screwed up.
As mentioned, if the "recalc all ratings" doesn't help, then you can check in the editor to see what some of those guys' stuff rating is under the covers to make sure their (raw) ratings are reasonable. Also feel free to play around with the global settings to see if you can kickstart stuff around.
Otherwise, you can always send over your files (
