Former Wisconsin linebacker Chris Borland shocked the NFL four months ago when he announced his retirement at the age of 24 -- despite his good health and hefty paycheck -- but he doesn't seem to harbor any regrets.

Borland recently spoke with the Milwaukee Journal Sentinel's Jeff Potrykus and said he's been most surprised by the number of times he's been asked how he could walk away from a $530,000 base salary. For him, it was all about priorities.

"People can't get over the money," said Borland, who returned three-quarters of his signing bonus. "That's all they think about. But your health is a little more important."

Borland, the 2013 Big Ten linebacker of the year, also reiterated just why he walked away from football in the first place.

"Just a combination of my own experience, along with a lot of data that is out there regarding long-term health effects of head injuries," said Borland, who suffered a concussion during the San Francisco 49ers' training camp but didn't tell team officials. "And I play a position and a style of play where I was susceptible to the worst of it.

"I played a physical brand of football and played through some things where it makes sense for me."

Borland told Potrykus that he doesn't quite know what he'll do next, but he's taking his time to decide. Next on the agenda is a trip to Europe.

A lot of players and analysts weighed in on Borland's retirement back in March -- some questioned the move; most supported it -- but the best take might have come from another former Big Ten player, Penn State's John Urschel.

Urschel, now an offensive lineman with the Baltimore Ravens, wrote that he envied Borland. Urschel is a mathematical genius who's had multiple papers published -- but he just can't quit. Even if, like Borland, he knows football isn't great for his brain.

"I play because I love the game. I love hitting people," Urschel wrote. "There’s a rush you get when you go out on the field, lay everything on the line and physically dominate the player across from you. This is a feeling I’m (for lack of a better word) addicted to, and I’m hard-pressed to find anywhere else."

It wasn't easy for Borland to retire early. But, four months later, it's good to see that he still believes he made the right decision.
