– Absolutely brutal penalty by Spencer Burford to end the quarter. That’s the first rest McCaffrey has gotten. – RB Elijah Mitchell makes an appearance with about a minute left in the first quarter. The 49ers might be able to get him with a double move at some point. – Steelers CB Patrick Peterson is sitting on in-breaking routes. There was no window to throw it to Aiyuk, so he brought it back and found RB Christian McCaffrey in the middle for an easy completion. – Really excellent play by Purdy to pump fake his first read to open the 49ers’ third drive. – Two plays into Pittsburgh’s third drive and Bosa hasn’t come off the field. That could swing this game at some point and will be something the 49ers need to clean up this year. – The Steelers are having a ton of success on kick returns. The preseason jitters appear to have subsided after some time off because of his injury. That moved his kick to 41 yards and he drilled it. – Moody’s first field goal try was blocked, but the Steelers were offsides. He found Kittle for a short completion, but third-and-14 isn’t where Purdy is going to thrive.

That’s the first time Purdy has been under duress. – Pressure from the Steelers gets home on a third-and-long. That was a nice throw by Purdy in the intermediate area of the field. – The 49ers get behind the sticks to open their second series, but Purdy found Aiyuk for 23 yards on second-and-11. If San Francisco’s defense turns the ball over at the rate they did last season it’s going to be really hard to beat the 49ers. – Now a turnover after Steelers WR Diontae Johnson slipped on a third-and-5 to give Charvarius Ward perhaps his easiest-ever interception. That’s why he’s the best off-ball LB in the sport. Fred Warner blew up Steelers RB Najee Harris to open Pittsburgh’s second drive. It could not have been more down the middle. That was a sensational drive that needed just seven plays to go 54 yards. Play-action on their first snap inside the 10 and Purdy hit WR Brandon Aiyuk for an eight-yard touchdown. That shows some of the trust he has in Purdy to make the right play on a fourth down. – Kyle Shanahan gets aggressive early with a fun design on a throw to George Kittle on fourth-and-1. – Easy throw for Brock Purdy to Deebo Samuel to open the 49ers’ first drive. – Ray-Ray McCloud is returning punts just four weeks after having wrist surgery. Nick Bosa played all three downs to open the game. Arik Armstead got pressure up the middle and Drake Jackson finished it off. – Deommodore Lenoir is the nickel CB, not Isaiah Oliver. – Heck of a play by Clelin Ferrell to snuff out a jet sweep. It wouldn’t be a surprise if Moody handles kickoffs moving forward. – Mitch Wishnowsky is handling kickoffs, not Jake Moody.
