we really don't have any "holes". but if anyone thinks this team is set i'd like to point out that under brad stevens this team has been bounced from the playoffs in the same manner each yr. they've made the playoffs.
we couldn't shoot, specifically in the last few mins of a close out game. so either we need to stop taking jump shots or get shooters in here.
...or add elite shooters/shot creators like Kyrie and Hayward. Last year was almost magical (getting to the Finals) based on who we actually had playing.
As for Horford, I am more than happy to keep him on as long as possible, but I think Hayward can provide everything (and more) that Horford can on offense. Defensively, we may need to look elsewhere, but hopefully Williams develops or we draft/trade for another elite big man prospect.
