Just based on this season? Current skills? Not projecting out?
If so, I'll go:
1. Allen
2. Wentz
3. Dak
4. Goff
5. Cam
This is ranking the individual QB's only. Not the talent around them on offense that can effect their play positively or negatively.
Before the season, I probably would have had Josh Allen #4 on this list. But the guy is looking great so far. He's probably #2 in the MVP race behind Russell Wilson after 2 games.
