I think the biggest thing in the Rockets favor for keeping that playoff spot is the lack of non-playoff teams in the West who have improved this offseason.
Sacramento are no better.
Phoenix haven't improved.
The Lakers still suck.
Nuggets have made no additions.
Pelicans do not look better either.
Utah is one team who have improved and they should take Dallas' playoff spot since Dallas have lost players and haven't added anyone yet.
That leaves Minnesota who should improve by virtue of their coaching change and gradual improvement of their young guys. I think it'll come down to a battle between the Wolves, Rockets and Blazers for the final two playoff spots in the West.
I have OKC, GSW, SAS, LAC, UTA, MEM as my top 6.
I have Lakers, Suns, Kings, Pelicans and Nuggets as my bottom 6. In that order.
