We could sit here and scream about how poor Boston’s defense has been inside the bubble. The Celtics own a defensive rating of 117.9 after their first three seeding games, and only one team has a worse mark (the helter-skelter Sixers).
We could lament Boston’s lethargy after the team whiffed Tuesday with a chance to essentially lock up the No. 3 seed while playing a Jimmy Butler-less Miami Heat team that was on the second night of a back-to-back.
Boston hasn’t played with any sort of consistent energy in its three games, falling behind early against Milwaukee, coughing up a big lead against Portland, and trying to play catchup all night against Miami.

But here’s one thought we couldn’t shake while watching Tuesday’s game: What a luxury it is for Miami to have a rookie like Tyler Herro on their bench. Herro chipped in 11 points over 22 minutes during the Heat’s 112-106 triumph.
With Marcus Smart in foul trouble — so much so that he fouled out late in the third quarter — Boston lacked a bench boost. Take away Enes Kanter’s 10 points and the Celtics’ reserve trio of Grant Williams, Brad Wanamaker, and Smart combined for 14 points on 4-of-18 shooting.
At one point during the second half, Celtics coach Brad Stevens dispatched Romeo Langford for his first seeding-game minutes but Langford turned in a scoreless 3 minutes, 44 seconds, in which he mostly blended into the scenery.
Herro, of course, went one spot ahead of Langford in the 2019 draft. There had been a buzz before draft night that the Celtics were fond of Herro and that he had impressed the team with his shooting in one of his workouts. There might have even been a few groans inside the Auerbach Center when Miami snagged the Kentucky product at No. 13.
The Celtics ultimately took Langford, who has no shortage of potential and might eventually be a better pro. But his rookie season got off to a slow start as he healed from hand surgery and then he dealt with a bunch of minor maladies that even limited how much floor time he got with the Maine Red Claws of the G-League.
Herro has now appeared in 50 games for Miami while shooting a robust 39 percent beyond the 3-point arc on 5.4 attempts per game. He wasn’t even Miami’s best rookie this season — that distinction goes to Kendrick Nunn — but Herro won Erik Spoelstra’s confidence and is now a key rotation piece while logging 26.9 minutes per game.
On Tuesday, Miami’s four-man bench combined for 43 points on 31 shots while each player logged at least 21 minutes of floor time. For Boston, Semi Ojeleye missed five of his six shots, including multiple open 3s. Smart finished 0-for-5 shooting.
Make no mistake, Boston will lean heavy on its core players when the playoffs arrive. When Kemba Walker is off his minute restriction, and combined with a hefty dose of Jayson Tatum, Jaylen Brown, and Gordon Hayward, that might leave only a small handful of minutes for reserves not named Smart.
Still, games like Tuesday night show how important it is to have players that can take the baton, even if it’s only on rare nights. None of Boston’s younger players have shown enough this year to earn Stevens’ unwavering trust.
Again, guys like Grant Williams and Langford could have bright futures. Maybe Carsen Edwards and Tremont Waters, too. That’s especially important for Boston because of how much money they have tied up long term in their core players.
But the fact of that matter is that, right now, none of Boston’s rookies have seized their opportunity, nor has 2018 first-round pick Robert Williams, who was only inserted late in Tuesday’s game to defend an inbounds attempt with his length and bounce.
Those players could get another chance to show what they’ve got on Wednesday when Boston plays a back-to-back against the Nets. With Walker set to rest his knee and Stevens unlikely to go too heavy on starter minutes in the team’s first (and only) bubble double, younger players will need to take advantage of whatever minutes come their way.
Herro won’t be the difference between a first-round upset and a first-round exit for Miami. But the Heat are well-positioned moving into the future because of the progress their youngest players made this season. It’s critical teams develop talent if they are going to commit most of their money to their top stars.
The Celtics are left waiting for their youngest players to show they are ready.
