Here's my breakdown of why I'm concerned when comparing this year to last:
1. CB1: DJ is a great CB2, especially in man coverage, but I'm not sold on him as a lockdown CB1. I see him as a slight downgrade from TH12.
2. Positional Downgrades: Based on limited tape from online videos, the rotation seems to be shaping up with RJ and Teon getting significant snaps. This creates a shuffle (TH12 -> DJ, DJ -> RJ, Colton -> Teon) where I believe we've gotten weaker at each spot. (I have no concerns about Preston, however—he's great).
3. Scheme Fit: If they stick with a man-heavy scheme, this secondary may not be as lockdown as last year's unit was.
To be clear, I'm not saying they will be bad, just that there are far more question marks this season.
