So first of all credit to Ryan Bernardoni (@dangercart on Twitter) who just had a long twitter thread basically outlining this idea, but I've been wondering about this to msyelf for months so here it goes.
I think the Celtics should strongly consider trading Gordon Hayward.
I think most C's fans can agree that Tatum, Brown, Hayward have payed at a roughly even level this year. Lets call them B+ guys. They're each good in differnet ways, but roughly equivalent. There's only one basketball right? So what is it that 3 B+ level guys will give you that 2+ level guys and a decent 3+D can't? What really would you be losing if you trade Gordon Hayward? Now you might rightly say "We don't lose much, but thats not a reaosn to do it you fool." To which I would respond with four points.
1) You likely can't keep all four of Kemba/Hayward/ and the Jays long term for money/luxury tax reasons. And yes, I know Wyc said the C's would pay the tax but 4 (near) max contracts is very, very, very diffcult to fit on a team long term.
2) Given their age and how they've played this year, you're kepeing the Jays. So it makes sense to give them a larger role and allow them to grow in it. Neither of them is as good a playamaker/passer as Hayward, but it might help to let them do more of it. Trading Hayward allows them to do that.
3) With or without Hayward probably doesnt change the ceiling of the team that much. I dont think you're winning a tittle with or without him. I think its also possible that having him, another guy who needs to eat on the floor can in fact in some cases lead to stagnant "you turn, my turn" offense. The net translation basically being the repetiitve skill set/talent level doesnt raise your ceiling enough to matter, and in the regular season may not even be worth say more than 3 wins.
4) Even if you think the C's can afford to keep Hayward long term, trading Hayward could give you the sallary fodder to upgrade in other areas. If he's not adding a whole lot to the team ceiling wise then doesnt it make to use his sallary to upgrade else where like bench, stretch big, or defensive center? Isnt it possible that subtratcing him and adding too those relatively weak points makes you better even if hes the best player in a deal?
So in conclusion you arent keeping him long term for money reasons. The Jays can probably replace alot of what you'd lose by trading him right now, and would be afforded increased developmental oppurtunities going forward (this point is critical). It desnt change your ultimate ceiling this year, while perhaps being a better use of resources that ultimately makes the team better (depending on the deal) in the long term.
I know conventional wisdom says its crazy. But I think it has to be considered. Now obviously if you truly believe this team is a real contender you probably dont do this, but I don't think its crazy.
