3. Richaun Holmes
Richaun Holmes is someone that Mavs fans have liked over the last few years, often pushing the front office to make a move for him.
Dallas finally made a move for him this summer, and he recognized the love that Mavs fans have given him over the last few years.
Mark Cuban even called the Holmes move "the most underrated pickup of the summer."
Despite the high expectations for Holmes, he hasn't produced much in his limited preseason action.
Through three preseason games, Holmes is a combined 1-7 from the field with just three rebounds. His poor play has almost guaranteed him the third center spot, as it looks like Dereck Lively II will be the starter, while Dwight Powell will be the first center off the bench.
People had mixed emotions when Holmes came to Dallas, as he was coming off a season in which he averaged 3.1 points per game. Was that because he was behind Domantas Sabonis or because his play had regressed?
It seems like both happened, and Holmes doesn't look like he will contribute much for the Mavs this year.
There is still plenty of time for him to get his footing in Dallas, and he could carve out a solid role for himself, but he hasn't looked the best so far.
