I'm not even sure I'd take Mahomes at this point. Lets see how he does when he's lost many of his weapons, has injuries to overcome and has to win despite his defense. Not saying he won't do it but now we'll get to really see what Mahomes is made of. We've already seen what Watson is made of.
The Texans had a much better defense than the Chiefs do now when Watson was getting the he!! beat out of him on a regular basis.
I still say Watson reminds me of a young Steve Young. Just like Young, Watson needs to improve/speed up his decision making like he has the last 2 weeks and do it consistently.
