At this point (season 30) my nerves are more about the unexpected curveballs from other people in the league.
The guy with an ADP around 100, who I hoped to get around round 8, and someone picks him in round 5.
Or a player with an ADP around 50 who’s still there in round 6, so I shift my strategy mid draft and go best player available.
Or the QB I think I can wait on, there’s a run on QB’s, and he’s gone earlier than I wanted to draft a QB.
You can do 1,000 mock drafts and it won’t prepare you for other people doing unexpected stuff.
