Prisoner of the moment type comment from him. Where was Zach Smith last week with that level of praise? Did one game suddenly make Hyatt the best WR in the country? No. That's just hyperbole at its finest.
Now, this is the kind of performance that will make people stand up and take notice, and he could be a superstar in the making. But if you believe he's suddenly the best WR in the nation, then he should have been on Smith's radar a week ago, too, but I'll bet you he (like many people making these same kind of comments) had little idea who Hyatt was before this performance.
