4. Nick Nurse
The Nick Nurse era has officially ended in Toronto. Rumors have already started circulating on Twitter about Nurse heading to another Texas team, as the Houston Rockets also have a coaching vacancy. That seems to be a questionable fit. Nurse has seen success coaching guys that are willing and capable defenders, and the Rockets have defensive liabilities everywhere you look.
The Spurs, on the other hand, have several young guys that have shown solid defensive prowess. A lot rests on the NBA Draft Lottery, but if Popovich retires and the Spurs get a better pick than Houston (maybe even landing Wembanyama), it would be tough for Nurse to turn down an offer in the 2-1-0.
