Both guys are years away from hitting their prime and have a lot of growth potential in them.
Disagree. Brown is in his 6th NBA season, and Tatum his 5th. It's inaccurate to call them "years away from hitting their prime." They're largely the players they're likely to be in style, strengths, and weaknesses, in all likelihood. Room for growth and improvement? Certainly. But they ain't prospects, either.
The problem isn't Tatum and Brown.
Maybe. Maybe not. You are what you're record says you are, and the recent positive trend has been with Brown in street clothes. As the team has transitioned to being the Js, they've regressed in record when sharing the floor. It's just a fact.
The problem is surrounding them with complimentary players that will make the team better than the sum of its parts and coaching bringing that team together.
Celtics have had a pretty large and wide variety of complimentary players in recent years. Heck, only Smart has been a consistent face in that crowd. Irving, Walker, Horford, Hayward, Morris, Fournier, etc etc. What didn't previous or current players offer that future ones will, when factoring our ability to acquire players with average-to-below-average assets to work with -- and when considered the assets listed above have largely been squandered, and draft picks have been suspect?
Patience is needed, something most of this site's posters have none of, most of the time.
The counter-argument to this is homerism, something most of this site's posters have plenty of. I'd rather not see either player traded, but what's the statute of limitations on mediocrity? If the Cs are a lottery team, or a first or second round exit team.... how long before they have to look in the mirror and proactively create a team that's ACTUALLY complimentary as a whole (not to both Tatum and Brown at once, who are not especially complimentary)?
Like, when will the JKJB crowd consider that might not be the best plan, if conditions remain as is -- even if he's a cool guy whose a good player and you like him alot?
This summer? This time next year? Next Summer? Will Tatum still be happy then if the Cs are a steady 6-8 seed?
