A tight end has to have a total skill set in this offense. And the Eagles have three of them and the coaching has taken the best of what each player does to create a promising symmetry that is as central to the scheme as any personnel grouping.
Brent Celek is the veteran force, the ultra-tough guy who someday will go down as one of the best in franchise history. He's worked so hard over the years to make himself a strong blocker to help in the running game and in pass protection, and at the same time continues to find cracks and crevices in defensive coverage to make himself a reliable target for quarterback Nick Foles.
Of the three, Celek is the most "traditional" tight end for a position that has morphed over the years. Today's tight end is more defined as a receiver proportioned to tower over defensive backs and to run past linebackers. Celek is 6-foot-4 and 255 pounds and he is still capable of big gains, but in his eighth season Celek is properly called a "move-the-chains pass catcher."
The Birds also have Zach Ertz and James Casey. Casey was mostly invisible last season and will still be behind Celek and Ertz this year. While Ertz is getting most of the attention in terms of fantasy value, Celek can't be forgotten and it's very possible he continues to be a factor in the offense. This could limit Ertz's potential again this year. But Ertz has six catches for 86 yards so far in preseason games and still looks poised to have a big year. Of the two, Ertz is the guy to target, at least leading into the season
