Christian McCaffrey

The 49ers signed undrafted rookie RB Cody Schrader. Schrader spent six years in college and will turn 25 in September. But he s coming off a massive 2023 season. After four years at Truman State, Schrader walked on at Missouri and immediately led the team with 745 rushing yards in 2022. Then he ripped off 1,627 rushing yards and 14 TDs on 5.9 yards per carry, plus 22 catches for 191 yards, this past year. Schrader led the SEC in rushing and was named a first-team All-American. He ranked 32nd among 157 qualifying RBs in Pro Football Focus rushing grades. Schrader is a sturdy 5 9, 202-pounder with good contact balance and strong leg drive. He s also reliable in the passing game as a receiver and protector. Schrader doesn t run with much wiggle, though, and bombed at the Combine with a 2.33 Relative Athletic Score. At his advanced age, it s fair to wonder how much meat is left on this bone. He s obviously a dynasty long shot after going undrafted and landing in Christian McCaffrey s backfield. We ll see if Schrader can make the team this summer.

In Christian McCaffrey, the 49ers have arguably the best running back in the NFL.

Isaac Guerendo clearly is a favorite of 49ers running backs coach Bobby Turner and a big fan of Christian McCaffrey.

The 49ers selected Louisville RB Isaac Guerendo in Round 4 of the NFL Draft. Guerendo battled hamstring and foot injuries at Wisconsin. When healthy, he sat behind Jonathan Taylor and fellow rookie Braelon Allen. So, after five years in Madison (and only 99 carries), Guerendo transferred to Lousiville in 2023. He shared the backfield with Jawhar Jordan, who actually led the team with 181 carries (vs. 132 for Guerendo). The duo posted nearly identical receiving lines: 22-234-0 for Guerendo and 21-246-1 for Jordan. Guerendo wins with an impressive combo of size, speed, and athleticism. The 221-pounder brings return value, too, with 714 career kick return yards. He was the talk of the NFL Combine after posting a ridiculous all-around workout. Consider this: Guerendo s 4.33 forty time, 129" broad jump, and 41.5" vertical jump all ranked in the 95th percentile or better among Combine RBs since 1999. Now, he doesn t always play up to those testing numbers. But that potential remains as he gains more reps. In San Francisco, Guerendo will be battling for scraps behind Christian McCaffrey. It s an awful spot for the rookie s short-term fantasy value. Landing with HC Kyle Shanahan helps the long-term outlook. McCaffrey turns 28 in June and is signed through 2025.
