Backup running backs with passing-down skills. One injury changes their value overnight, and you know the role immediately.
We always talk about this week's flex, but I want the player who matters in December. My nomination is Harbor City's rookie tight end: low snap count now, excellent blocking grades, and the veteran ahead of him has an expiring deal. He may be useless for six weeks, then suddenly run every route. Who is your favorite patient stash, and how long can you justify the roster spot?
