Should I Start Isaac Guerendo in Week 17? Fantasy Football Start 'Em, Sit 'Em Picks

Isaac Guerendo - Fantasy Football Rankings, NFL Injury News, DFS Lineup Picks

The San Francisco 49ers playoff hopes might be over, but your fantasy football championship dreams may still be intact!

If you have San Francisco tailback Isaac Guerendo on your roster, you may be wondering if he's worthy of a start this week against the Detroit Lions.

So, what is Guerendo's fantasy football outlook moving forward? Should you start him in Week 17?

Be sure to check all of our fantasy football rankings for 2025:

 

Isaac Guerendo Fantasy Football Outlook

The Niners' run game was nearly non-existent last week as Patrick Taylor Jr. was only able to produce 24 yards on eight carries and Deebo Samuel added 25 on five carries. San Francisco will welcome back Guerendo to the starting lineup for Monday night's game against the Lions with open arms as he's easily the most talented runner they have left on the active roster.

Guerendo has averaged 5.2 yards per attempt this season, racking up 381 yards on the ground and another 87 yards as a receiver. He's been very efficient with his touches and showed some explosiveness when he gets to the second level.

Guerendo should handle the bulk of the touches for the Niners this week, firmly putting him into fantasy consideration.

 

Should I Start Isaac Guerendo in Week 17?

The matchup against Detroit looks bad on paper as the Lions have been very stingy against the run this season. However, Detroit's defense has been decimated by injuries in recent weeks and they have been much softer against the run lately than they were earlier in the season.

James Cook ran for over 100 yards against Detroit, while Josh Jacobs rolled up three touchdowns against them, too.

The biggest issue for Guerendo could be that the Niners' offensive line is also banged up.

If the Niners can't establish the run with this unit, then the game script could be a negative one for Guerendo - though he does have some chops as a pass-catcher, too.

Ultimately, he's a very risky play that should only be deployed if there are no safer options available. It's very much a boom/bust spot for Guerendo and having to rely on him in the final game of the week is suboptimal.
