I'm not so sure Rozier has 10-15 value, but let's say he does in a vacuum, which teams in that range are going to trade their pick for Rozier? If no one moves up in the lottery these are the teams with picks 10-15
Philadelphia, Charlotte, LA Clippers x2, Denver, and Washington
None of those teams need a PG, especially one with Rozier's skill set.
Now 16 and the Suns might be a decent chance, but if they take Doncic with their own pick, then I think Rozier becomes much less a need.
17 is the Bucks. That is a team that could theoretically use a young PG to take over down the line for Bledsoe. After the Bucks and rounding out the top 20, are the Spurs (unlikely), Hawks (unlikely), and Wolves (possible).
So I'd guess that if Rozier's value is 10-20, then the only realistic landing spots are Milwaukee at 17 and Minnesota at 20, with an outside shot at Phoenix at 16. A bunch of teams in the low 20's make sense, but I just don't see that as enough value for what Rozier can do for the team next year (and frankly I'm not sure 20 would be either).
