McCaffrey remains unproven backup; avoid in early drafts despite outside role opportunity.

McCaffrey, a third-year receiver and former No. 100 overall pick out of Rice, has totaled just 29 receptions for 371 yards and three touchdowns in 26 career games and has been used primarily as a backup. He entered the league as an unpolished receiver after spending his first three college years as a QB and has run 20+ routes in only five career games. He'll likely see most of his work on the outside this season, but fantasy managers should temper expectations, as he should not be on draft boards to start the year.
