5. Not eligible to be traded yet: Derrick Jones Jr.
One of the Dallas Mavericks' best offseason pickups this offseason was signing Derrick Jones Jr. to a veteran's minimum contract. It was unclear how much he would play in Dallas at the time of the signing, but he has been one of the Mavs' best players through the first quarter of the season.
In 22 games, Jones Jr. is averaging 9.9 points, 3.8 rebounds, 1.0 assists, 0.6 steals, and 0.9 blocks per game while shooting 49.7 percent from the field and 38.7 percent from downtown. He has been an outstanding shooter thus far, and his improvement in this area has allowed him to become a vital piece to the rotation.
On defense, Jones Jr. is excellent on the perimeter and oftentimes takes the best player on the floor. He fears no one and has the frame to guard multiple positions.
Another great part about Jones Jr.'s game is his ability to score in transition. He is a freak athlete and is always a threat to throw down a ferocious slam. Jones Jr. is also a great cutter and is a good weak-side lob threat.
Jones Jr. has easily become one of the best veteran minimum signings in the NBA, and Dallas should do whatever they can to avoid trading him. He will be eligible to be traded starting Friday, but it wouldn't be smart for Dallas.
