Well let's break this down by position.
QB: Equal, no significant change
WR: Improved, hard to believe but I think this group is better
RB: Improved, youth was improved
TE: Improved, Smith is an upgrade on paper, nothing else is changed
OL: Incomplete, this is tricky because you need rookies and Free Agents to step up, I wanted to say equal but it is "unknown" so graded accordingly.
So with the O, improved on paper....,
The D is..........well, tricky...... I need some time to think on this. I want to lean toward improved to be honest I can also say incomplete.
Edge/OLB, as with the OL it will depend on a few younger guys, Chop and Phillips and Chubb's recovery from injury so = incomplete
CB is equal, I was in the camp that Howard needed to be gone two years ago or moved to slot. His lack of suiters tells you all you need to know.
SS = this probably equal also and it depends on the system that is installed.
LB = improved, Long and Brooks will be just fine in the middle.
DL = here it is, the elephant in the room, is Wilkins departure gonna be huge or is the money ball approach gonna look genius. IDK = incomplete.
If the line play improves or is equal on both sides of the ball, the team is improved. If the line play is worse on both sides, the team is going to be worse. Line play will be the key to the improved or worse aspect of this entire team, trenches for the win.
