No clue what we need to do for backup PG until we see how Jenkins does in the playoffs.
I know nothing about the draft after the top 3 guys.
It's sort of fluid, but Detroit will most likely only have the MLE and BAE to spend on free agents this summer. Those numbers will be set when the salary cap is set. But MLE should be around $15-16 million and BAE just short of $6 million.
This shows you every teams upcoming draft picks.
