Isaiah Wynn is very good when he is healthy - and excellent in the running game. Here we are in year three. Wynn needs to be doing everything the training and strength/conditioning staffs are asking of him.
A line of Wynn - Thuney - Andrews - Mason - Cannon can be excellent, but there are injury concerns throughout. I like the depth that BB added to the OL in the draft. I think they are still one veteran tackle away from having complete puzzle up front.
As for the receiving corps, my feeling is that the Patriots are one solid veteran WR away from being a solid group as well. If one of the the rookie tight ends can contribute 40+ receptions as a safety valve for Stidham, they'll be fine. There were so many rookie WRs drafted high, there will be a number of good veterans let go this summer.
I have faith in Edelman to be a leader and mentor in that WR room and help Harry and Meyers reach their potential. Sanu is a good receiver and a full training camp will be major factor in his role.
The thing about this team is that they have veteran leadership at every position group except tight end. When I look around the division, I see loads of talent but nowhere near the veteran leadership that the Patriots have. This team won't get rattled by anybody and will know how to stay in the moment.
