ALLEN PARK -- The Detroit Lions added a couple offensive linemen in the early rounds of Bob Quinn's first draft, and the unit didn't get better. So they added two more in free agency last year. And then they got worse.
Sure, injuries hurt. There's no escaping that. But their offensive line coach also didn't do a good job. There's no escaping that either.
There's a reason Ron Prince was the only assistant fired when the season ended. And there's a reason Jeff Davidson was hired to replace him.
Prince was an old-school coach. That's one way of saying he was intense, and some would say to a fault.
