NFL Week 1 grades: Trey Lance and 49ers get a 'D' after upset loss, Dolphins get an 'A' for thrashing Patriots

Here are the Week 1 grades for every team that played on Sunday

After only one game with Trey Lance under center, the San Francisco 49ers might already be regretting their decision to send Jimmy Garoppolo to the bench. 

In his first start since officially being named 49ers quarterback, Lance had a disastrous performance in a shocking 19-10 loss to the Bears in Chicago. Sure, it didn't help that the game was played in the middle of a biblical rain storm, but no matter how you spin it, it was any ugly game for Lance. 

The second-year quarterback completed under 50% of his passes (13 of 28) and threw for just 164 yards. The troubling part for the 49ers is that Lance wasn't able to come through when the 49ers needed him most. With the 49ers trailing 13-10 in the fourth quarter, Lance had the chance to engineer a comeback, but any hope of that happening ended when he threw an ugly interception to Eddie Jackson that basically iced the win for Chicago.
