This young core of JT-JB is very good. They’ve been successful 3 out of 4 years they’ve been together and they made the finals last year. So the dilemma is, do you run it back given they made the finals or do you make some changes to the rotation?
I’m generally leaning towards the latter but you don’t do it blindly. You need to build around JT-JB (in particular, JT) in a way that maximizes them. Now, how do you build around a versatile superstar wing? If we follow how the other championship or contending teams did it (Kawhi’s Raps, KD’s Big 3 Nets, Lebron’s Cavs, Dirk’s Mavs), the general shell looks like:
Offense:
1) the versatile superstar scorer (Tatum)
2) an outside threat to release the pressure (Horford?)
3) a vertical (or inside) threat to diversify the attack (Timelord)
4) a playmaker to control the team and get guys to their spots (Smart?)
5) either a shooter, a scorer, a cutter. At most, a team can survive having 1 non-threat on the floor (JB, as a microwave scorer)
Defense:
1) a strong paint presence for rebounds and altering shots (Timelord)
2) a swiss knife elite defender who can take on the team’s best player (Smart or even JB)
3) other defenders that are as switchable as possible
Timelord and Jaylen Brown are great fits and the big question marks imo are: 1) can Horford continue to play at a high level (and consistent shooting) like we saw in the playoffs and 2) can Smart improving on his playmaking skills?
A deep bench wins you games in the regular season and hopefully gets you to the playoffs as healthy as possible but rotations are shortened to an extreme in the playoffs. You need your main guys firing.
