Obviously there has been the rumour of Daryl Morey, negotiationing with Stevens, for Ben Simmons... but if I'm looking correctly at the current NBA landscape and the fact that Portland look in no way a contender, perhaps it is inevitable that Damian Lillard will be traded to Philadelphia for Simmons.
If you look for the correlation of teams that would want Lillard and have the right assets to offer Portland, there is only one options in my eyes...the 76ers.
This may have all been game of cat and mouse for Morey, especially considering that the best way to improve the Trail Blazers and keep Lilliard happy, would be moving CJ McCollum for...Ben Simmons.
