Guerendo is going to miss some time at camp and with the rookie out of action, it could mean the RB2 role ends up going to Mitchell or Mason. Mitchell struggles to stay healthy at times, but has excelled in the starting role before. It could just be coach-speak about Mason, but it's also worth paying attention to, especially if you're looking to handcuff McCaffrey this season.

It's always tough for rookies when they miss time in camp. Guerendo was said to be battling for the RB2 spot with the often-injured Mitchell. The Niners traded up to get Guerendo who was having a nice spring. Meanwhile at WR, the team got back Pearsall today but Cowing was trying to work his up with the depth chart as well.

Reigning Offensive Player of the Year Christian McCaffrey once again has reset the RB market, signing a two-year extension with the 49ers, averaging $19 million per year.

McCaffrey will receive an additional $8 million over what he was scheduled to make in the first two years while adding $24 million in guarantees.

McCaffrey solidifies himself on one of the best offenses in the league, and should still be viewed as the best RB option in fantasy football.
