I'm pretty sure in previous years you couldn't change Pickems after the Knockout Stage was locked. This might be helpful for people that might underestimate some teams.
You are correct! This is a small change we made this year to help keep Pick'em interesting throughout the tournament.
Also, it definitely wasn't targeted at anyone (me) who always misses all their quarters picks (nope) and then ragequits before semis even begin (never).
