My advise would be to not use heisman difficulty when recruiting. You will get cheated just like if you play on heisman when playing the ai. The BIG difference is that you can get by playing the ai on heisman when using an elite team or if you have really good stick skills.
You dont have none of that when recruiting.
Sim a whole season and only do recruiting to see if it's too easy. If its too easy on the default varsity level bump it up to All American.
Heisman is just biased when playing the ai or recruiting against the ai. The BIG difference is that you can get by playing the ai on heisman when using an elite team or if you have really good stick skills.
