A couple things I do to try and fill my bench are:
1) Backup QB and as mentioned, look at the bye week matchup.
2) Backup RB's, at least a couple and I will try to handcuff one of my starters.
3) Backup WR's, look at a team depth chart and until the very late rounds there is always a starter or 2 out there that haven't been selected. Might be a bad team but a starter is a starter when you need a backup.
4) K and Def are always my very late picks and never pick a backup.
Hope it helps and good luck!
