Re: What can I get for these 3 guys?
You should be able to get Nash or Calderon for those guys, and probably Deron as well. Getting an elite player is always a great thing, but you've got to have some depth on your team to handle the loss of the two other starters you're dealing, and each of those guys bring unique things (Harris points+steals+assists+ft%, Chandler fg%+boards+blocks, Crawford threes+points+ft%+assists). List the rest of your team so we can see who you'd be plugging in to the holes.
Thing is, getting a guy like Nash will get you as many assists as Harris and Crawford combined, so you need to crunch numbers before making a deal this significant.
