It is completely within your right to feel that way.
It's most likely nonsense but that is quite OK. You are coming off a SB win and should be very optimistic.
But ...
I will offer a few notes.
PFF ranked DBs by team and scored the Eagles 1 spot BELOW Dallas.
As a note Patrick Robinson was BY FAR the Eagles highest graded CB last year.
Nickel cornerback: Patrick Robinson, 89.8
18. Philadelphia Eagles
Projected starting lineup:
Starting cornerback: Ronald Darby, 84.2 grade ---added note here that Darby is the buddy of Jameis caught up in BOTH his sexual assault stories. If the NFL views him an accessory they could suspend him as well.
Safety: Malcolm Jenkins, 84.1
Safety: Rodney McLeod, 79.4
Starting cornerback: Jalen Mills, 77.1
Nickel cornerback: Sidney Jones, 47.2 --Jones is a longer shot than the Cowboys Jaylon Smith. He's returning form injury after a very weak performance in a couple chances before being shut back down last year.
The loss of slot cornerback Patrick Robinson and the question marks his absence leaves cannot be understated. With all the draft picks in recent years at the corner position, no one besides Darby should be safe in their starting spot. The good news is that their is so much competition, the bad news is that none graded higher than Mills’ 77.1 overall grade a season ago.
17. Dallas Cowboys
Projected starting lineup:
Starting cornerback: Chidobe Awuzie, 81.7 grade
Safety: Jeff Heath, 80.8
Safety: Xavier Woods, 78.8
Starting cornerback: Byron Jones, 76.8
Nickel cornerback: Jourdan Lewis, 79.6
2017 was always going to have some growing pains with as many youngsters as the Cowboys had in their secondary, while 2018 though offers much more promise. Rookies Woods (78.8), Awuzie (81.7) and Lewis (79.6) all impressed when given a shot. If any or all improve on their rookie-season form, Dallas’ secondary could end up ranked much higher than 17th by the end of the season.
At TE you signed Rodgers to a vet min deal, lol. He may hold off Dallas to start because he can block a bit at least but he is not good. You lost a young, promising guy that signed for 4Y/32M.
And you lost a long-time pro to boot in Celek. The total TE depth chart has regressed. It cna bounce back if Dallas is any good but he is a rookie coming from a low level of college football. You saw Wentz year 1 versus year 2.
On the DL you lost Jernigan who was a starter 4-6 months. You lost a steady Vinny Curry and yes replaced him with a seeming upgrade... except Bennett has a FELONY arraignment scheduled in like a week.
The possibility of losing him to suspension looms very large.
From a Dallas Cowboys standpoint they aren't projected to be a title favorite by any means. They are young across the board.
They have young, ascending players in about 15 of the 22 starting positions.
But they have a ton of cap space going forward, and some young talented best of position type guys like Martin, Zeke, DLaw.
