It's probably a combination of things. First, they believe he's a descending player with health issues. Second, they think there's someone on the roster that can do as well as Sitton at the guard position. Third, there's someone that they believe has enough upside on the roster that they don't want to cut. You can bet that MM and TT both came to this decision. It probably was not something that Sitton said to someone in the front office. It comes down to what they believe the best 53 will be.
