McCaffrey unproven backup with minimal route experience; avoid in early drafts.

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. The source notes he entered the league as an unpolished receiver after spending his first three college years as a QB, and has run 20 or more routes in only five career games. He is expected to see most of his work on the outside this season, but the source explicitly states: 'fantasy managers should temper expectations for both McCaffrey and Williams out of the gate, as neither should be on draft boards to start the year.'
