Josh Allen is very easily a top 5 quarterback in the NFL. Depending on who you ask, he might actually be number 1 on that list. Most of those folks are probably Bills fans, but still. Allen is great.
Nobody throws with the power he does. He spins it in ways other people can’t. He nearly had the Bills in the AFC Title game behind his arm talent. That’s how good he is.
So, yeah. Losing a guy of that caliber? It’ll, of course, sink your season before it even gets started. That’s exactly why Bills fans were all in panic mode after Allen hilariously flopped while being tackled at training camp.
