The first preseason game for the 49ers is in the books.

The team fought back after trailing 9-17 at the start of the fourth quarter with some impressive offensive execution. It ended with a 27-17 victory in Kansas City over the Chiefs, and now it’s onto the next game with the Broncos.

However, some good and bad points need addressing before Denver comes to Levi’s Stadium. With that in mind, let’s take a look at what San Francisco needs to take away from that first exhibition.

The Starters Dropped the Ball (Especially on Offense)

It started rough for the 49ers on the very first play against the Chiefs. Alex Smith dropped back and threw it deep to Tyreek Hill for 32 yards on the very first play. Keep in mind that Rashard Robinson (our best cornerback) was on Hill.

The starting defense did make up for it with the next drive they faced when Robinson intercepted Smith thanks to Solomon Thomas’ pressure on the quarterback.

Unfortunately, that would only muster three points after another three-and-out for the starting offense.

Hyde had zero yards on the ground. Hoyer was one-for-four passing the ball for only three yards. The starting offense needs to address these issues before they face Von Miller and company next.

Both Foster and Thomas impressed in their first game

Reuben Foster was all over the field tackling and breaking up passes. Thomas is the reason for the game’s only interception because of his quarterback pressure on Alex Smith.

These two are already meshing together and making an impact. Expect these two to keep this up for the remaining preseason games.

The Backups were the real stars in this one

Matt Barkley looked poised in the pocket coming in after Hoyer faltered. Beathard ended up being the game MVP with his phenomenal performance.

All three of the running backs behind Hyde was able to get a yard. In fact, all three of them had 40 or more yards each. With the notable one being Joe Williams with an 8.6 yard per carrying average on seven carries (60). The team might need to re-open the running back competition discussion.

Receivers like Aldrick Robinson and Kendrick Bourne showcased what they can do. Especially in getting yards after the catch.

Most importantly, Aaron Lynch is getting back into the discussion of being a starter on the defense again. He came out and had a two sack game in the short amount of time he played.
