I think Philly and Miami probably got better for this year, even miami maybe a meehhhhhh.
Philly I think is an odd case of getting what they needed (floor spacing) without actually getting what they needed. The problem with Philly is that when their best lineup is on the floor, it doesn't work well together. The Embiid-Horford-Harris-Richardson-Simmons lineup just doesn't work. At the very least, Brown hasn't found a way to make it work. So unless Brown decides to have Horford run the bench mob (which was the prevailing wisdom after the signing) and goes Embiid-Harris-Richardson-Thybulle-Simmons, I just don't see these additions doing much. Their both mediocre rotation floor spreaders that don't defend well. Their spacing issue wasn't a lack of outside shooting threats (Harris, Richardson, Thybulle, Korkmaz, Burke, Neto, Scott can all space and hit the 3), it was the inability of their big unit to function together.
As for the Heat...I don't know if 36 yr old, chilling out for the last 8 months Iggy is the get. I haven't seen Gallo confirmed, he's the add that would have scared me. Miami is going to be a tough out, but I kind of question the ceiling of any team where Butler is the big offensive threat. Dude is a great two way player, but when your offensive game is based on getting to the line (shooting 25% from outside this year...), I think you're limited in the playoffs.
Clips kinda mehhhh maybe it works out maybe not.
Clips are a big swing and a miss for me at the deadline. Gave up too much for veteran trash. Thomas is way done, and though Morris fixes some of their scoring depth issues I was talking about the other day, he's ass defensively and doesn't do a whole lot other than chuck.
GSW improve for when they are healthy.
If they can't fix Wiggins, he can't be fixed.
