Patrick Peterson has been a busy man of late, attending multiple charity events last weekend and hosting his own on Saturday and Sunday.

The star cornerback has still kept up with the Cardinals' roster moves, and after the addition of Pro Bowlers Chandler Jones and Evan Mathis last week, Peterson reached out to General Manager Steve Keim.

"He made a huge, huge splash early," Peterson said from his celebrity golf tournament on Sunday at the Camelback Golf Club. "When I saw it on Pro Football Talk, I texted him like, 'Whoa. Wow.'"

Keim shot back a confident response.

"He texted back, 'Booyah, baby,'" Peterson said.

While Peterson and his teammates continue to enjoy their offseason downtime, there is a palpable buzz about the Cardinals around the league. NFL Network analyst Nate Burleson puts Arizona among the upper echelon teams, and points to the Jones addition as a difference-maker.

"In this division you've got to get after quarterbacks – specifically Russell Wilson," Burleson said. "A guy like Chandler, who's rangy, he can not only come off the edge and attack any quarterback, but you can drop him in coverage. You can put him in spy situations where he's really delegated to watch Russ and contain him."

Peterson said he's excited to have the double-digit sack man pressuring the quarterback, which can make everyone else's job easier.

"Over the years, our pedigree has been blitz, blitz, blitz, blitz," Peterson said. "Now that we have (edge rushers) that can just pin their ears back and go after the quarterback, it's going to be fun."

MATHIEU HAPPY WITH REHAB PROGRESS

Safety Tyrann Mathieu has shared periodic updates on social media as he rehabilitates from last year's torn ACL, and he continues to feel positive about the recovery.

This injury isn't as severe as his season-ender as a rookie because that involved more torn ligaments. Mathieu is hoping to return at some point this offseason.

"Week-to-week, I'm making great strides," Mathieu said.

He took a golf swing at coach Bruce Arians' charity tournament last weekend and reported no ill effects.

"My knee was fine," Mathieu said with a laugh. "I've been doing all kind of movements, different kinds of things. I think I'm smart enough not to put myself in harm's way."

PETERSON'S CHARITY IMPACT

This was the first celebrity golf tournament Peterson hosted for his Patrick Peterson Foundation For Success, and he hopes it can be "a marquee fundraiser" each year. He also had a welcome reception and silent auction at the Penske Racing Museum in Phoenix on Saturday night.

Peterson was named the Cardinals' Man of the Year in 2015 for his off-field charity work, and he continues to be humbled by the feedback he gets from the families he helps support.

"It kind of makes you blush when you hear those types of stories," Peterson said. "'I did that?' So I think it's pretty cool to give these kids, these families, these parents, a helping hand to help the kids turn the corner and be successful."
