It's not just about the QB, we were a team theoretically built around an elite offense and an average or so defense.
We lost our top 7ish QB and our OL was completely ravaged with injuries. Dak, Tyron and Collins are 3 of our top 7ish players overall and all have more or less missed the entire year, Martin is slated to miss half the year and he's a top 3-4 player on the team.
So that's 3 of our top 5 and 4 of our top 7-8 players on the roster missing most or all of the season.
The Skins and Giants were never built the same way, they were never going to win with offense, so losing their shitty QBs for a few games doesn't have as much of an impact.
What happened to us would be like if the Skins had lost Da'ron Payne, Chase Young and Jonathan Allen for the year, or if the Giants had lost Leonard Williams, Dalvin Tomlinson and Dexter Lawrence for the year.
Take those 3 off each team and let's see how they'd look.
