INDIANAPOLIS — The Arizona Cardinals have a big decision to make on former LSU star Tyrann Mathieu looming in a couple of weeks. 

If Mathieu is still on the roster on March 14 and there are no changes to his contract, the safety and nickel back is scheduled to make $18.75 million next season, a steep price to pay for any non-quarterback. 

Cardinals general manager Steve Keim was non-committal on Mathieu's future when asked whether or not Arizona was operating as if Mathieu will be on the roster this season. 

"It's what we are doing right now with the coaching staff, looking not only at Tyrann but every player, and see how they fit," Keim said. "How they fit what we are asking them to do schematically, and how they fit from a salary standpoint, all those things moving forward, and there are a lot of moving parts. What we are potentially doing in free agency, how it affects the cap, and I feel we have a pretty good grasp on that."

Mathieu responded to an analysis of Keim's comments by posting 'It's a business' on Twitter, and the tweet caught the attention of at least one Saint.

Saints wide receiver Michael Thomas was ready with his own pitch to Mathieu, a New Orleans native who played his high school football at St. Augustine. 

"Come to the BLOCK, where all we trying to do is win every game and not get caught up in weirdo stuff," Thomas tweeted. 

Mathieu would likely be one of the hottest targets on the market, but he'd also be a perfect replacement if strong safety Kenny Vaccaro leaves in free agency. 

Fully recovered after tearing his ACL in 2016, Mathieu played more snaps than any player in the NFL in 2017 and picked up 78 tackles, a sack and two interceptions.
