When the Eagles drafted tight end Zach Ertz in 2013, they already had the 27-year-old Brent Celek and had just signed free agent James Casey.
Chip Kelly, then the Eagles coach, was asked how he would be able to get all three on the field.
“You go like that,” Kelly said as he held three fingers up in the air, “and three tight ends go in the game. … If they go three linebackers, we spread them out and if they go [with defensive backs], we smash you. So, pick your poison.”
While Kelly didn’t exactly use his three-tight end personnel package very much, the decision to expend a second-round selection on Ertz was a sound one.
