From the first list I would sign Horford or Durant no questions asked (obviously). I'm only signing Whiteside if we do some back ground digging and eventually feel confident he won't misbehave if he gets paid. I'd be fine with Dwight but not at the money he would want.
Dudley, and Teletovic seem like great bench options.
Bazemore is a good idea if we are moving one of our guards in a trade, but I think he's probably going to make way more than i'd be comfortable paying.
Jamal Crawford is too old, Ryan Anderson has too much injury risk.
I'd love Barnes, I think he's the type of guy who won't be worth his contract initially but by the end he will be good value.
