Alternate DITR - all players eligible for DITRs. Some players might just get 1 or 2 ratings improved. Pitcher improves 1 pitch. Slugger bulks up, etc.
I think this would alleviate a lot of complaints about DITRs without randomizing the draft process. Currently, DITR gains are awarded almost exclusively to 1B/DH/C types and pitchers whose OVR project up to about 60. Sometimes the gains turn a marginal player into a potential big leaguer (but usually not, which is fine), but it'd be more exciting if occasionally prospects who have "empty" OVR projections in the 70s might get boosts in one or two areas, turning them into potential starters or better. This would still reward owners who spent time ranking draft prospects, rather than awarding random gifts.
