Canales says that's by design and part of what he's working to build here, with players competing.
"We talk about it all the time; we make us," Canales said. "It's the matchups every day at practice that make us who we are. And if you look at what we've done up front over the last couple of free agencies that draft, just getting great players up front on both sides to challenge each other, certainly on the perimeter, TMac going against Mike Jackson, going against Jaycee Horn just makes him better at the line of scrimmage.
"When you got two big guys who can run, and they're fundamentally sound, it makes you elevate your game. That's exactly what we want, and we try to create that in every room."
And as it pertains to McMillan, there are signs of progress toward that goal for Canales as well.
"I think it's just his consistent ability to win at the top of the route; he uses his hands well. He's got great body control for having that kind of frame in size," Canales said. "A lot of times, guys do struggle with people in their space. And for a 6-4 guy to be able to control his body and then come back to the ball, he's such a friendly target because he attacks it whenever it's thrown to him. You'll see him come back towards the ball versus just receiving it, if you will. So those are some of the things that I'm excited about, you know, just continuing to see from him."
