Complete camp coverage: 2017 football primer

Navon Mosley was on the back hash when he saw the quarterback ready to throw to the opposite sideline in a recent camp practice. So he stuck his foot in the ground and booked it.

Mosley reached the receiver, running a go route, and the ball just in time to swat it down.

“That was just a good play, just a flash of things I can do,” Mosley said earlier this week. “I’ve just got to keep doing that, keep my eyes good, just breaking off the quarterback, and I can be really special.”

Purdue certainly hopes so.

Because on the same day Mosley relayed that play, secondary coach Anthony Poindexter was saying moments later that the Boilermakers aren’t confident they have a player who can play free safety well enough “in the post.”

And Poindexter said it’s holding the defense back.

“We really don’t have an experienced post player,” Poindexter said.

Mosley can’t take offense to that statement because even though he technically was Purdue’s starting free safety for much of last season — as a true freshman — his role was completely different.
