I just don't think Celts would be willing to match like a 17mil/season+ offer either. So many salary commitments already and they just don't have room for him when they're fully healthy. He's just exactly what the Kings need at the 4, especially with Keegan showing he can play the wing full-time.
I just keep going back and forth with Barnes and his long-term use with the Kings. He's such a good player when he's locked in and stays aggressive, but we're at like a 3-year trend now where he's like an elite 20 PPG scorer for a 8 game stretch and then is just perfectly fine fading back into being a low USG C&S spacer. So if Barnes isn't going to stay consistent offensively, I'd be very tempted to go get the massive upgrade on defense with Grant and still maintain the spacing with how Grant has shot the 3 the last 3 seasons. Also something to be said about adding a piece in Grant Williams, who is the same age as the rest of the core and won't be 25 until next season. So we'd have a real 3+ year window where we'd have the core locked up, assuming Monk and Sabonis re-up the following off-season. That's fairly exciting prospect as well
