Former NFL defensive lineman Jovan Haye (@jovan_haye)  joined Jeff Thurn on Thursday’s edition of Overtime on ESPN 99.1. 

To hear Thurn's conversation with Haye, listen below:

How much of the NFL was mental vs. physical? 

"I think 90 percent is mental and 10 percent is physical. Because everybody is physically gifted. It's the mental part. Some of the greatest players, that you know, athletes that don't make it that long because mental side either staying in the past or living life right. Knowing your playbook, a lot of these guys struggle. So, sometimes you see athletes that are not the most athletic, last the longest because mentally they are strongest."
