Even though some expect Kelly's offense to be an exact replica of the one he ran at Oregon, there will be some key differences.
We're not too sure what they are yet, considering most of it will unfold once the season gets underway.
But one thing that could come to light in training camp is how exactly Kelly utilizes his tight ends—both from a positional standpoint and also selecting personnel.
What's meant by a "positional standpoint" is how Kelly will use the tight end, what situations they'll be called on during games and if the position will transform into more of a wide receiver role.
The latter is definitely possible, which is just another reason why the position is worth noting during training camp.
Also, new faces like Zach Ertz and James Casey could determine the futures of Brent Celek and Clay Harbor.
Celek, who garnered the second-most targets last year for the Eagles, could have some of his looks taken away by the two newcomers.
And as for Harbor, there's a strong potential that he gets cut by the end of camp.
On a positive note, it'll be intriguing to see what Casey, a jack-of-all-trades previously for the Texans, brings to the table and how the athletic Ertz fares in developing his blocking skills.
