Josh Allen's poor play obviously did not get them a win today. And Tua's "normal" play got us a win every bit as much as our O-Line's poor play did, and our defensive execution on third down did. At some point, we are going to have to stop making excuses for Tua's average play by saying, "well Tua won and player X lost". I mean, is that what we are going to be hanging our hats on? That Tua will win ugly enough times to get us to a Super Bowl? If you are trying to say you'd rather have Tua over Josh Allen right now, there's not much I can say to that.
Using that logic I guess players like Trent Dilfer, Jeff Hostetler, Mark Rypien, and Brad Johnson are all better than Dan Marino.
