49ers Studs and Duds: Where has this Deebo Samuel been all season?

You can’t fault the 49ers’ effort in Sunday’s 29-17 loss to the Dolphins.

You can, however, knock the team’s execution — or lack thereof — in the loss.

The 49ers had ample opportunities to win in South Florida — and it’s clear they wanted to win — yet 11 penalties for 90 yards, a missed field goal and terrible situational play on both sides of the ball did San Francisco in.

Have we heard that from the 49ers before?

Oh, right, we’ve heard it nearly every week this season.
