4. Quentin Grimes
Cost to acquire him: Second-round pick(s), matching salary, rotation piece
Making an outright trade for New York Knicks guard Quentin Grimes would be challenging because of his small salary, but the Knicks and the potential team that makes a trade for him could each throw in a piece or two to help the money match up.
The Dallas Mavericks are a team that has shown interest in Grimes, and his defensive approach could be an intriguing piece for the Mavs. This season for New York, Grimes is averaging 7.2 points, 1.9 rebounds, 1.1 assists, 0.7 steals, and 0.1 blocks per game while shooting 39.5 percent from the field and 36.4 percent from 3-point range.
Grimes plays with great energy on defense, and he has shown flashes that he can be a solid scorer as well. He attacks the rim well and is a great shooter off the catch.
Defensively, Grimes has quick feet and switches well. He has a similar playstyle to Josh Green, and he could be a good piece for the Mavs off the bench. A trade for Grimes doesn't make much sense if the Mavs don't trade one of their guards in the process, but his defense and 3-point shooting would help the Mavs down the stretch.
