I think this team is as many here have said before me, two pieces away from being a true contender. Maybe some pieces should be moved in order to make this happen. It's still very early and things will definitely improve but the signs are obvious. I don't know how much better we can be on defence with the current players even when on full throtle. With all the talent offensively that LBJ,Love and Kyrie bring to the table, i think this team needs a defencive sg/pg combo that doesn't require the ball on offence and he can shoot the occasional 3's along with a good rim protector. Pg is by far the most stacked position in this nba era and Kyrie will struggle when he will have to guard score-first pgs (and there are alot of them). It would be nice if we could switch him on defence and let him guard the less dangerous opponent guard. A rim protector is the second major upgrade this team needs as none of our current bigs can do that.
Do we have the assets to trade for such players? Is there cap space for them? I don't know the asnwer on these questions, but this defence issue has to be solved somehow. If we account for Lbj as being a plus defender, we need another two good ones to counter balance for Love's,Kyrie's defenciencies on this end. And ofc more commitment on defence from all the players in the team.
