The 2013 team may have still had an elite offense with Gronk, Edelman, Vereen, and Amendola all healthy. The 2019 team has all of their skill players...they just aren’t good.
Looking solely at skill players the main difference between the 2013 and 2019 team would be Gronk. And even he only played 6.5 games that year.
With the rest I'd give the 2019 team the clear edge over what we had in 2013. The RBs are hands down better, the WR group has more potential if Brady had consistently more time and Watson/LaCosse beats Matthew Mulligan/Hooman. Brady plays at a higher level as well.
The real limiting issue for this year has become the OL with only Thuney performing at a high level. Wynn looks good but lacks the experience to use his toolkit in a more nuanced way against all different kind of rushers, the center position is a cluster**** of injury and the right side of the line has turned into a nightmare (relative to last year).
All of this has become sort of a multiplier for issues in other areas (WRs sometimes really all covered, Brady sometimes being inaccurate or not seeing someone open).
If I was meeting here for the first time and she told me she was one of biggest models of all time, I'd be like "Sure lady and I'm the president" lol. For me her face is like 6.5/10 at best
