Panthers coach Ron Rivera insists No. 2 TE Ben Hartsock is a good complement to Greg Olsen. Hartsock is a mediocre blocker and a liability in the passing game. But to hear Rivera tell it, he's a key piece. "You look at his catches, they're all on the underneath routes - the quick ins, the quick outs. People miss the value of that when you have one tight end that can stretch the field and the other one that can attack the middle." Greg Olsen is going to push for 90-plus percent of the snaps once again this year.
