You guys have it all wrong; if we trade Rozier, it has to be for draft picks as assets to upgrade our Davis offer 7/1.
What draft picks are we going to get for him? I doubt we're getting a first rounder. How about trading him for a player under contract next year who can be used to contribute to matching salaries for Davis? Ideally a guy who can even help us this year.
I think Phoenix is an ideal trading partner. Something like:
Phoenix: Rozier, Yabu
Boston: Troy Daniels, Milwaukee's 2019 1st round pick (protected 1-3 and 17-30 in 2019; 1-7 in 2020; and unprotected in 2021)
Daniels would be a good addition for us as a shooter off the bench this year, and the Milwaukee pick would be a good addition to the AD trade, especially with the Sacramento pick continuing to lose value as they win more.
Further, between the salary savings in this deal and finding a team to take and waive Bird, you come really close to being under the taxpayer threshold, though I don't think that this quite gets us there.
