The 2025 1st is worth trading if the return is Banner 18, even if Poetl walks. So sick of people overrating late first-rounders. Had we dealt Kyrie and a 1st for Kawhi, we would already have Banner 18 instead of Toronto with a title.
It's not so much about overvaluing late first rounders as it is leaving yourself with no first round picks to trade until 2027, and Poeltl isn't the type of player who guarantees you a championship.
One of the things that makes Boston interesting is that this summer they can make what's basically a full-boat offer of draft picks if a fringe star on a rebuilding team comes available while most of the other contenders owe picks out into the future. Stevens has done an excellent job of adding Horford, White, and Brogdon all for "this years' first" for three drafts in a row, all while keeping the future relatively clean. Unless you genuinely believe that Poeltl guarantees a title, it'd be hard for me to take Boston out of the conversation for much better players when you can likely get a workable center for Pritchard and seconds.
Also, for what it's worth, I recall the Kawhi package being Jaylen, Smart, and a first or two. Given that all the locker room problems would have still been there and that Kawhi isn't exactly a take-over-the-locker-room type, I don't lose any sleep over passing on that deal. Likeliest scenario there is that Philly or Milwaukee win the title that season and Boston's in a much worse spot going forward.
