Stats don't tell the whole story.
If Celts are so good with Hayward then why is the Celtic record just 16-10 when Hayward is playing?
This may get mis-interpreted by some as blaming Smart, but ... well, unfortunately there have been several games where we played Smart and Hayward together a lot due to injuries to Jaylen and/or Kemba. And unfortunately, the effect up above gets neutralized somewhat when Hayward plays with Smart because Smart handles the ball a lot. In fact, with Smart on the floor with Hayward, the team plays somewhat worse on offense.
Kemba, Jaylen & Jayson all defer to Gordon a ton for playmaking. But with Smart, Brad has him handle the ball because he is less effective as a 'space-maker' without the ball. Teams like the Bucks notoriously sag way off of Marcus unless he has the ball. So this forces Hayward into the corner as a spot-up shooter and negates much of his play-making.
Just watching this current game right now against MEM, with Jaylen out, and Smart moved up to the starting lineup, we see the same effect. The starters struggled to generate offense out of the gate. What little they did was off Hayward (4 assists already before the end of the 1st) but the ball spending too much time in other people's hands.
This team needs to be healthy and with everyone in their proper role.
Important - please don't take this post as a knock against Smart. I love Marcus and he's super valuable to this team. But he and Gordon don't mix optimally on offense. I like Smart best when he's the playmaker for the bench.
Interesting take, as always. And I do think that you’re seeing something real. But color me skeptical about your conclusion; and whatever it is that you’re looking at, the sample size isn’t big enough (that’s a caveat, not a refutation).
Consider:
1) Smart’s Usage is only 17.9%;
2) There are two distinct kinds of lineups when Smart and Hayward have appeared together: with Kemba and without, meaning when Marcus isn’t the primary ballhandler, and when he is. The offensive performance of those two groups of lineups is very different.
a) The most often used lineup with those two together also has Kemba: Walker-Smart-Tatum-Hayward-Theis. That one has played together 75.9 minutes, and has an offensive efficiency of 1.11 (defensive 1.01).
b) The second and third most often used lineups with those two together does not have Kemba: i) Smart-Brown-Tatum-Hayward-Theis. That one has played together 43.4 minutes, and has an offensive efficiency of .99 (defensive 1.12); and ii) Smart-Brown-Tatum-Hayward-Kanter. That one has played together 19.1 minutes, and has an offensive efficiency of 0.95 (defensive 1.08).
c) The fourth most often used lineup with those two together also has Kemba: Walker-Smart-Brown-Tatum-Hayward. That one has played together 12.4 minutes, and has a stellar offensive efficiency of 1.24 (defensive 1.00).
That last one has a minuscule sample size, but in fact none of these four represents a lot of possessions.
The point is clear enough. Smart/Hayward, apparently, is an excellent offensive pairing, as long as there is a point guard in the lineup along with them (or maybe only as long as Walker is with them, or...). I offer this to you with a grain of salt.
