Two thoughts:
1. D1 coaches are definitely scavenging senior transfers in an attempt to game the new EE system. A variety of relatively minor tweaks could alleviate the problem: those mentioned above, using player personality to demand PT be guaranteed, or moving the 5 EE cap to 6.
2. Why is the so called "greed" rating being dropped? I'll grant that it should count for very little, but I assume that it exists to give some indication during recruiting on the likelihood of EE or transfer and the effectiveness of booster gifts. [Correct me if I'm wrong.] That gives the game depth and the players a bit of personality. A coach could even attempt to target high-end recruits that are unlikely to go EE on one end of the spectrum and another coach could target kids that won't report him for all the throwback jerseys, but will be one-and-done, on the other end.
IMHO, the better path is to clean up the recruiting messages that no longer mean anything (to keep noobs from getting confused), but leave some personality rating in effect to have some impact once the coach is at the D1 level. Certainly, recruiting functions like the Psych Opinion should be unavailable at D3 and the Personality Test probably only at D1. If the "greed" rating, or hidden ratings like it, have no relevance, then why not get rid of those two functions altogether and drain the game of any color?
