As for that FA list, about a dozen guys I'd be interestd in. Depending on salary/contract demands.
Saric and Jerami Grant are good buy low candidates, but since both play PF where Randle is ensconced, they aren't priorities. I'd take either for cheap. Say $6M Saric and $9M Grant.
PG's:
check out the FVV market. He's shrimpy but tough. Sort of a Jameer Nelson type.
RegJax for cheap. He's always injured and not that great a starter. But for cheap, can roll the dice.
Conley? A vet, but short PG's don't age well. Utah should have been a great fit.
Word is out on Bertrans, so likely pricey. But My Leonard and Frank Tank are 7' shooters who could be had cheap. We need shhoting. Probably just 15-20 min a night guys. But both have talent. $5M for these guys should be bargains.
Other shooters:
Bogdanx2
Malik Beasley
Dillon Brooks has really blossomed, but an RFA and I assume Griz ain't getting outbid for him.
