I hear what your saying, but who are the celtics trading for Simmons. Horford? RICHARDSON? those guys already played for Philly and the sucked.
The 3 teams I mentioned have very real trade potential. Russell, Irving, and Porter Jr. Obviously the Twolves need to add picks or other assets, but all three teams have a chance with those assets.
Per fanspo.com,
''Josh Richardson cannot be traded this year since he signed an extension after August 6th''. Agreed that the Sixers would probably have zero interest in Horford. Chances are it would have to be a 3-way trade. Here's a deal I'd be happy with.

Smart cannot be traded till January 20. Schroder cannot be traded till December 14.
If we trade for Simmons (which I don't think we will), I'd be perfectly OK parting ways with Timelord. The 2 of them would be a terrible fit next to each other.
PG: Pritchard (perfect fit next to Simmons)
SG: Brown
SF: Tatum
PF: Simmons
C: Horford
This would be a championship-caliber team in my book.
