Phil Parker knows that corner depth is important. He talked about a pair of defensive backs that are starting to emerge in the secondary per 247Sports’ David Eickholt.

T.J. Hall and Jamison Heinz are on the second team at the moment, but have been getting more and more reps at practice recently. Heinz and Hall have combined for 3 total tackles.

“I guess you look at Heinz and TJ Hall, they’ve been working,” said Parker. “This is a good week that we had. The last two days of practice they got a lot of reps here to show that they’re improving and stepping forward to what they have to do.”

At the end of the day, Parker knows that Heinz and Hall can can even better. He plans on pushing them more and more throughout the season.

“Are they exactly where I want them to be? No. I mean, that’s why they’re 2s, right? Hopefully we can push them and keep on pushing them.”
