The Houston Rockets had the best offseason in the NBA, so I don't want to ring any alarm bells; but if there's one area to fear that could be the undoing for this team, it's uncertainty and lack of depth in the backcourt.
If Reed Sheppard shakes off a rough rookie year early on and proves that he's capable of being an NBA role player, this could become a non-issue and the Rockets could roll in the Western Conference. But if Sheppard struggles again in year two (he averaged just 12.6 minutes per game in 52 appearances last year) then Houston might have a bit of a crunch in the backcourt, because the combination of Sheppard, Fred VanVleet and Aaron Holiday could leave a little to be desired.
