That would be a horrible fit of Wade in Cleveland. First, they don't need anymore injury-prone players in addition to what they already got. Second, where does Wade fit in the offense? As we saw all season long, the Cavs' entire offense is Lebron or Kyrie ISO, which necessitates having a shooter at the 2. Wade is by no means a shooter, and though he's good with off-the-ball movement, he largely needs the ball in his hands to be effective. Now Shump isn't a knock-down shooter by any means either, but he's a better three point shooter than Wade and doesn't need the ball to be effective. Furthermore, at this stage in his career Wade is not as good as Shump defensively, and per their respective salaries, Shump can provide a similar amount of production at a much smaller price.
