I agree, but is Kyrie by himself better than Russell and whoever else they might be able to get alongside Russell (not to mention Kyrie will be paid much more money in a cap year)? I also think Kyrie is a cancer and not much of a winner, so, yeah, I don't know. Seems like out of all the guys on the FA market this year, that's the guy you put lowest on the max list for them.
Also, 1st rounders are only valuable when they become good players, and that is highly tied to the position of the 1st and a ton of luck. I doubt a likely-rebuilding team is parting with a top-10 pick for Dinwiddie, and if it's not that, it's a light-year from equal-value.
