I've asked myself this dozens of times over the past 4 years:
Would I rather watch a team that goes 25-57 and is rebuilding? (again)
Would I rather watch a team that goes 50-32 and you know will not go far in the postseason with Embiid?
I keep going back to option #1. Look at what OKC has done after shedding all of those contracts. They are one of the best teams in the Association and are the youngest #1 seed EVER. Their average age is 23 years, 9 months. That's ridiculous. It's a model that a certain baseball team in Maryland has done pretty well with as well.
I hope...and hope...and hope - that #21 is gone. This/he ain't working.
