And if they screw DCX!
I'm a regular listener to the ESPN Fantasy Focus podcast, they had a segment yesterday with a fantasy commissioner that secretly edited his roster moves so that he could pick up Bryce Harper and went back and put him in his lineup after he hit his first homer so he could get credit for it. They said he should be stripped of commissioner power, stripped 1 of 3 keepers, Bryce Harper's stats were removed from his stat line and Harper is ineligible to be picked up by anyone in the league. IIRC we were pretty lenient on DCX comparatively.
I imagine DCX's penalties would have been much more severe if there was money on the line.
