He needs to get better yet, even better than he played today. If he doesn't, he won't lead any team anywhere special.
He was making plays, but the way in which he made them doesn't instill confidence in you that he can keep making those plays consistently. I think that is why a lot of people are hesitant to go all in on him as the Bills franchise QB.
I wish he would develop better as a pocket passer so that he was a more complete QB. If he did, he could really be an elite QB. As he is now, he is flashy good and sometimes flashy bad.
