49ers Studios, the San Francisco 49ers' in-house production studio, quickly pushed out a mic'd up video from Saturday's practice, the first of training camp. It features second-year tackle Mike McGlinchey welcoming his quarterback, Jimmy Garoppolo, back to the offensive huddle, and on-field hair discussion with tight end George Kittle.

Maybe the best line from the video was guard Mike Person saying, "Mike has a mic, talking to Mike, and Mike is telling about Mike's mic."

"It's Inception," responds McGlinchey.

Tackle Joe Staley, who is entering season number 13 with the 49ers, had his daughters on hand to watch practice. Here is a photo of the three of them observing from a sideline.

As if that wasn't precious enough, Staley showed Chris Biderman of the Sacramento Bee this homemade sign his five-year-old daughter, Grace, made. It gives props to her father's team, not so much to their Bay Area (for now) rival, and bashes the division rival Seattle Seahawks.

No word on where the disdain for the Denver Broncos comes from. Maybe don't tell general manager John Lynch about that. Or head coach Kyle Shanahan, whose father, Mike, was on hand for practice.
