Yes, yes the Ducks can beat Utah without Bo Nix.

 

However, I deal in "probabilities", and the probability that Oregon wins without Bo is not good.

Ducks cannot beat Utah without Nix playing the whole game.  As others have written, offense has not been able to generate even a few 1st downs when Ty has played.  Of course, even with Nix defense will have play much better and coaches will have to avoid decisions that  are very questionable if Ducks are to have a chance against a good Utah team that has handled Oregon recently.  Let’s hope for a surprise win.
