Strikeout is correct to a certain extent. A good DITR is pretty rare. Most of them that make the MLB are going to be at the bottom of the roster. However, if you can get one (or a handful) that is a good candidate, you could save yourself some money over the longhaul. Those guys that are role players can cost a 2nd round pick in the draft or between 3.5 to 6 million in the international free agent market. Or, as a comparison to the Free Agent market, they still save you money because even if you wait until your targeted free agents only demand a one year contract, you are probably still going to pay them between 1 and 2 million a year to play a role for one year. Compare that to paying a DITR 350k for four years and you are saving some money. It may or may not be worth the work, but that is up to each owner.
Right now, I have three DITR players on my Arizona MLB roster. One is my first baseman. He had high makeup, power and batter's eye, but everything else was horribly low. He plays a decent 1b, hits for power and since he is a switch hitter, he is adequate on my team. I have a RF that probably shouldn't get many at bats, but he did last season due to injuries on my team. I will be releasing him this year because he wants too much in ARB. My third DITR is my 4th starting pitcher. He is decent. So, those guys have definitely saved money that last few seasons.
I certainly would not discourage you from trying it. If you do try it, I would hope that you report your progress.
Thanks for posting.
