With very little to go on aside from Mitchell’s setback and ST duties, I’d take a guess at :
Edelman
Hogan
Matthews
Patterson
Berrios
Berrios seems like a great guy and talented and determined and all that, but here are some numbers: 27, 25, 25. These are the ages of Welker, Amendola, and Edelman when they had their first really solid season as a pro.
I am not saying Berrios "can't" do it, but how likely is it that he will come into the most difficult system in the NFL and do something that these 3 other guys took several extra years to do.
Plus do the Pats have the luxury of giving a roster spot to a guy in a group (while deep) has some big question marks? The odds of JE playing 16 games are slim. After Hogan we have Patterson and Matthews who have never played a snap in this system.
Plus Berrios has full PS eligibility none of the guys ahead of him do. But if he stands out in camp. He could make it.
With that said - My guess is that:
JE
CH
JM
CP
Are all making the team.
I think Britt makes it too. He has stood out at OTA.
PUP Mitchell - no brainer unless it looks like CP and JM flame out and MM is even healthy enough to contribute.
If they keep a 6th WR its coming down to Dorsett and Berrios. I know they like Dorsett and this has been stated many times. Matthews is a slot WR and dorset has elite speed.
Also, If the other guys work out I could see them moving JE into a more DA role where his snaps are more controlled so that he can remain more healthy for the playoffs.
