I set up a mock draft via Yahoo to simulate the later rounds of a keeper league draft (picks 100-220). We can adjust that number on both ends, so like picks 81-220 or 100-250 or both, depending on how managers feel. The league info is:
ID# 210640
Title: Keeper League Practice
Password: sushi (all lowercase)
The league scoring is 5x5 and is currently set up for 10 managers
If there is an easier way to run the mock draft than Yahoo, or suggestions about the setup for the draft, please let me know.
