Someone else will know this, but my recollection is that the potential pool of DITRs is culled from draft picks signed after a certain round and with potential overall ratings below a certain number. Some owners sign fewer draft picks than others, relying instead on tryout camp players and minor league free agents to fill their minor league rosters.
I don't think it has anything to do with draft picks; I've had plenty of tryout camp DitRs. Not that that's a good thing.
Just from my observation, I think it's a rare, random event (~2-3% per prospect per year) among all prospects 24 or under with "true" projected OVR less than a certain number, which I think is in the high 50s. I have tried to rank players higher for the draft with projected OVR in the high 50s who for whatever reason (usually low DUR or ST) would become valuable after a DitR, but no player I've ever drafted for that reason has been lucky enough to get one.
