I will say to have it as late as possible to avoid summer injuries that may occur and affect draft rankings but before actual drafting. I think by august 1st or Sept 1st, I'll have to look at the olympic schedule since that is a prime area where players may get injured. Though since there is only 9 rounds to draft vs. a full 13, we could push it later.
But the earliest would be August 1st.
Congrats on the win, it was well deserved
