The San Antonio Spurs are famously a very deep team and always have been. Their roster always has talent coming off the bench, and the second unit has always excelled, sometimes outplaying the starting lineup.
With one of the biggest offseasons in franchise history currently underway, predicting the Spurs' starting five for next season is no easy task, and assuming who will play a key role off the bench is even harder. However, I’m not convinced that any shocking free agent signings will join the Spurs only to be relegated to the bench.
Personally, I think the Spurs would be wise to give the young guys the keys to the bench. Let some recent draft picks or players who have spent their first few years riding the bench step in. Of course, having a second unit average of 22 years old is simply not prudent or sustainable. In fact, it’s somewhat reckless. The second unit, in my mind, needs to make up for areas the starting five lack in.
The Spurs were one of the worst teams in the NBA when it came from shooting from deep, so having a few deep threats on the court at once will be a refreshing change of pace. However, the second unit should also play hardy, defensive basketball. It's the Spurs way, and it works. Defense and shooting should be a priority.
