Who are our two-way guys this upcoming year? Davison and Peterson, with space for one more?
JD and Petersen are our current 2 ways. I assume Watson gets the third spot. I don?t know how we?ll get to keep Ramsey unless he challenges for the 15th roster spot?
This is all correct, as I understand it. But 2-way deals are not guaranteed. There is nothing to stop the Celtics from waiving Peterson (for example) and giving a 2-way to Ramsey. I am not sure how likely something like this is, but I don't think any of the 2-way spots are necessarily in stone or settled.
The Celtics will not waive Peterson based on two weeks of summer league. It would be a bad look for them. If he gets completely outplayed in training camp, maybe, but not summer league, and not two weeks after he signed a deal. The normal thing would be to convert him to an NBA spot and then give him some cash before releasing him, but that is expensive with the luxury tax this year, so it is much less likely.
I am not necessarily saying anything would happen based only on Summer League. They can carry up to 21 into training camp, right? That would include roster contracts, 2-way contracts, and exhibit 10 contracts. I think the Celtics are at 14/2/2, total 18 right now. So as far as waiting until after training camp or preseason, sure, no need to waive anyone before that (unless you want to give them a chance to latch on somewhere else).
But if someone who is on an Exhibit 10 contract is clearly playing better and has more ceiling than Peterson or another 2-way contract player, I think they would make changes. Summer league performance by someone like Ramsey may get them a Exhibit 10 contract and an invite to camp which could eventually lead to winning a 2-way deal. Probably not terribly likely, but possible.
