Carmelo for Avery Bradley Jerebko Johnson & BOS/MEM 1st
2012-2013 Carmelo led the league in scoring (29ppg 7rpg), led the knicks to the 2nd seed in the east (with noone around him), and was 3rd in MVP voting as the starting PF. Carmelo is 6-8 240lb's so hes a small ball PF whose not small. Playing the PF IMO would also infinitely better suit him defensively.
Lineup:
Isaiah
Smart
Crowder
Anthony
Horford
Anthony was the best player every time he played for team USA. I understand the skepticism on defense but IMO the "ball stopper" "iso" tags are a function of the team he plays for. I think hes more than capable of fitting into a team system.
I just don't give up Bradley for Melo without getting a SG in return. Leaves the backcourt way too thin.
So I might alter your trade to be
Anthony, Lee, Plumlee
for
Bradley, Johnson, Young, Zeller, BOS 2018 1st
I'd throw in Boston's 2019 1st or the Memphis 1st if we could get O'Quinn (which means Jerekbo is added and Young stays in Boston or they can have him if they want him). If need be for either trade I'd probably add in an extra 1st if that was the deal breaker.
So post-trade (without O'Quinn and 1 open roster spot)
PG - Thomas, Rozier, Jackson
SG - Smart, Lee, Green
SF - Crowder, Brown
PF - Anthony, Olynyk, Jerekbo, Mickey
C - Horford, Plumlee
That team is the clear #2 team in the East and would pose a lot more problems for the Cavs then the current team.
