I'm not talking about in the playoffs...I'm talking the last two games of the season. At this point there is far less to gain than there is to lose, in this situation, by putting Tony in. If Tony plays even mediocre, then there will be another controversy (manufactured or otherwise). If he plays like garbage, which is just a likely, then any trade value he may have had is then gone. At this point in Tony's career, I doubt he needs many reps to come in and be serviceable, should Dak go down with an injury.
At the end of day, though, I'm not resting Dak at all. He needs all the reps he can get.
