Brad has 2 2024 Firsts (Bos/GSW) to use at the trade deadline. That could land a really good TOP8/rotational player.These things are a bit flexible. I'd say 7 is the minimum number of guys you can count on to get through a full playoff run, 8 is better (because even if everyone is healthy, foul trouble and matchup issues do happen), but 9 is an ideal number because injuries do happen, especially on a team in which 4 of your top 7 are major health risks. Even taking Brogdon (and Tatum in game 7) into account, I don't think we'll get better injury luck in 2024.
FWIW this past year we had an 8 man rotation, with Grant being the 8th man (18 mpg, but did get 5 DNPs) and no one else playing more than 7 mpg, but that was with the rotation missing exactly one total game due to injury. In 2022, 9 guys saw real minutes, with Pritchard and Theis (13 mpg each, with some DNPs mixed in) at the end, and no one else getting more than a handful of minutes. TL, Horford, White and Smart missed a lot of time (12 combined games), meaning we absolutely needed 9 guys we could trust in the playoffs. I think that happens again this year, meaning we will absolutely need at least 2 of Pritchard/Hauser/Brissett/Walsh/Banton to step up, or we need real production from someone acquired via trade or buyout later in the year.
In a limited role, bench snipers like Hauser/Pritchard shouldn't really scare us. It's not like they would see any minutes in an elimination game (unless they earn that nod during the regular season, which is an outside possibility)
This is the best 7 they have had since they hoisted their last banner. Potential injuries are the Celtics' biggest roadblock.
