"Showing interest in" Austin Rivers is pretty benign. Of course they are looking into a range of options. Rivers is an 11 year NBA veteran who has started 184 regular season games in his career. I don't see the need for him but it is no shame to say he is potentially better than Pritchard. He is certainly better than Davison.
With the signing of likely to be new fan favorite Jay Scrubb to a 2-way, it seems to me that Champangie is even more likely to be waived or added to a trade. Scrubb can sit at the end of the bench with the towels and give us at least as much as was expected from Champagnie. So if Rivers is added, he would replace Champagnie, not Pritchard. I don't see it happening, but it is a reasonable option to at least check in on.
If we can get Giles on a 2-way, to me, that would be a real nice add. He has the potential to play into a back up PF role. If we can get him in and have a good long look, while still keeping the TPE and the last roster spot open, that allows for a good look at Giles and then the flexibility to go after a vet later, if Giles does not hold up. I think we need a bench PF piece, but we don't need it right at the start of the season.
