If Tracy Walker carries over his success in limited action from last season to full-time duties this season, the Lions secondary is immediately better than 2018. Matt Patricia adores safety-heavy sets and Walker covers a ton of ground. Stats that wade in the 70-something tackles and 5-ish interception waters, would be adequate enough to push the Lions over the hump. He’s also clutch at the end of games. Number 47’s success is super, super crucial to the Lions’ success this season.
