4. According to Kyle Shanahan, the 49ers veterans have started a daily "rookie hype man" program. Each practice, it sounds like there will be a new first-year player who will be tasked with getting fans pumped up before stretching starts. Today it was Mike McGlinchey who ran through the stands like a mad man. He set the bar very high for whoever is next.

5. Matt Breida had a very impressive run during the first team period that got a rise out of the fans in attendance. He took a run to the right for about 10 yards before bouncing it back to the left. Breida sprinted almost all the way to the left sideline while being pursued by a few 49ers defensive backs. He's an explosive runner that is good for one head-turning play each day.

6. Joe Williams also had a nice run during the same period. He took the ball straight up the middle and juked a defender in the middle of the field on his way to a big gain.

7. Aaron Burbridge flashed twice on Friday. He had two catches, one over the middle on a pass from C.J. Beathard and another near the right sideline on a ball from Garoppolo.
