The Dallas Mavericks are in desperate need of help around the him, both on the offensive and defensive end. Jakob Poeltl would solve that problem immediately. But the Mavericks can’t just sign him because a) they’d have to clear space to do so and b) it’s unlikely the Toronto Raptors let him leave.
Poeltl was sent to the San Antonio Spurs as part of the Kawhi Leonard trade and has been languishing on the River Walk the past few years. But last season the Raptors, in a similar situation as the Mavericks, needed a competent big man on their roster, so they shipped a first-round pick, Khem Birch, and some second-round picks to the Spurs to bring Poeltl home.
