Ertz has had seasons that have tripled and quadrupled Knox's production lol and it's not like that was only 5 years ago...it's been within 2 years.
For whatever reason, you don't believe a Quarterback or injuries makes a difference.
Beane sounds like he was satisfied with the Tight End position.
“We just never really got that position,” Bills General Manager Brandon Beane said. “At the end of the year, I thought we did a little bit. Dawson started to get his groove. But it was never where the opposing defense was like, ‘Man, we’ve got to stop their tight ends from going off.’ So we’ll look to that group.”
