So Gordon Hayward clearly seems to be the most likely big-time free agent that we could land this summer. However, even if we landed him, we're still going to be a starting PF short of a complete, championship-level squad (unless you think we'd go super small with IT, AB, Jae, Hayward, and Al, which I don't think is smart or realistic).
So let's assume that we end up using AB as trade bait to try and find that starting 4, slotting Hayward in AB's spot at the 2. That leaves us with the following lineup:
PG: IT, Rozier
SG: Hayward, Smart
SF: Crowder, Brown
PF: ?, Yab?
C: Al, Zizic
This assumes that we have AB and all of our picks, including this year's Brooklyn pick, on the table for a trade for a PF. Let's also assume that any guys off the bench and Crowder are capable of being included in a trade, too.
So what kind of trade scenarios do you see that we can use to find our other starting big in this scenario? Looking around the league, I see very few possibilities here outside of going super small, which isn't ideal. I think this is one of the problems with a Hayward pursuit - even with him, we still have other pieces to fill around him that are hard to find.
