I mean for NCAA/Madden. The way the ratins (and unity) work is fan-fucking-tastic.
I'll use the example of my PG. He's a 74 overall. In my league (NEC) he's a top 5 player and is a threat to go for 20-25 every night. He averaged 16.6 a night, without me making any attempt to inflate stats (putting in junk baskets in blowouts etc...)
What's great is this:
He has a very good layup rating, but he has a terrible shoot in traffirc rating. He misses a lot of layups in traffic, but he's solid with a good look.
He has a relatively low 3 point rating, but a very good clutch rating. He's hit several late 3's to tie the game...despite being a medicore(ish) 3 point shooter.
He has a decent dunk rating, but he can't dunk in traffic. One, he doesn't have the vertical. Two, he has the aforementioned shot in traffic problem.
What's great is how all the ratings work together. His layup rating doesn't make him a stud in the paint, because he can't shoot in traffic. He can't jam over 6'8 power forwards because he can't jump high enough.
He gets most of his points on the break....coming off a screen....or using an isolation. He has a decent mid range 3, and hits a few 3's....but mostly he's looking for space and trying to drive.
You don't get that level of difference in EA games. That's why every player feels the same, except for speed (more or less).
