NFL Week 2 fantasy flex rankings: Top streamers, starts

Another fantasy football season, another year where Christian McCaffrey is a top player.

The San Francisco 49ers running back had an OK performance in the season opener, a 27-7 handling of the Los Angeles Rams. He posted 10 carries for 68 yards on the ground and five catches for 20 yards receiving. After a day of rest, he is expected to excel in the Week 2 matchup, a home game against the lowly Miami Dolphins.
