On one hand, the 2nd half of the season was validation of everything that the Celtics have been doing. That run proved that trading away Rajon Rondo and Jeff Green were probably the right moves. It proved that trading for Isaiah Thomas was a steal. It proved that Brad Stevens is a heck of an NBA coach. It proved that there's a lot of good, young talent on this Celtics team.
On the other hand, the first round sweep at the hands of the Cavaliers proved a few things as well. It proved that the Celtics don't have the talent to hang with the best in the league. They have lots of solid rotation guys - guys that you want on your side in a tight game or series - but no stars to carry them. That's gotta change if they want to compete for championships soon.
That leads us to the offseason. The Celtics have an incredible amount of options available to them. They've got a plethora of current and future draft picks. They've got cap space and an ownership group that's willing to spend money for top notch talent. And they've got an array of tradable players and trade exceptions that their very creative GM can move for the right opportunities.
That last phrase is key though. It has to be the right fit. They can't and won't throw money at players just to spend the money. They shouldn't be trading to make sideways moves that aren't an ideal fit. They have to make the right moves for the right players that will fit into what we're trying to do here.
With all that said, this team need more talent. One way or another, they need to get players with a lot more talent.
Bottom line: Expect changes coming this summer.
