What Smith was impressed with, though, was the big gain-turned-run by rookie running back Ashton Jeanty early in team drills, albeit against a skeleton Niners D-line.
Jeanty burst through a hole on the left side, between Miller at left tackle and left guard Dylan Parham, and raced untouched for about 20 yards.
"It was something we did yesterday and we didn't really get it right," Smith said. "And then today he came out, we got it perfect. And I thought, 'Man, we took a big jump just from yesterday to today.'
"And to see that from a rookie player, he learns and he grows with every single experience. ... That's something that's going to make him so much \[more\] of a great player, because he's getting better by \[the\] day. And so, I thought Ashton did a great job as always, but he definitely took another step and another jump today."
So what if it came against a makeshift D-line in a controlled scrimmage of a joint practice in front of fans on a triple-digit heat day.
It happened, and it was a positive for the Raiders.
"It's just really classy work to get," said Raiders coach Pete Carroll, who was scampering between fields to take in as much live action as possible. "We'll make evaluations and figure that out once we get a chance to watch the film.
"We come here to play good football and get better. And I think both sides did a great job of showing that."
49ers coach Kyle Shanahan, who said he was missing 20 players due to injury, agreed.
"In the team periods, you can feel Maxx every play," Shanahan said. "It's fun to watch the 1-on-1s when we do that stuff. … That's usually my favorite things, the 1-on-1s, when you can isolate on those guys."
As far as the Raiders are concerned, their true opponents, even at this stage of training camp, are still themselves. And to be able to work against someone, anyone, in a different colored jersey is a bonus.
Especially when your guys trying to make the roster win the last play of the day against their guys trying to make the roster. And on a Hail Mary, to boot?
Yeah, many prayers are still waiting to be answered.
