I'd suggest either:
A 2010s draft - as we draw this decade to a close 2010-2019, drafting best XIs from this decade - simple concept but could be fun and been a while since we've done such a simple draft
or
Not sure on exactly how it would work but:
A managers draft, so either a manager per round, and we draft players who played under that manager, or we each choose a manager and create a team in their image.
In this idea, I prefer the former, so we'd have 11 managers (open to suggestions for them) and we go from there.
I think as we only have a week to get a draft together, the first one would be easiest to get people excited by.
Thoughts?
