I watched the entire game except for some of the second quarter when I took my kid to get a pumpkin. He wasn't really doubled teamed much, sometimes a cover 2 safety over the top. The corner, who I tried to look up but couldn't find, pretty much shut him down. I didn't see anything about him that looked like it would be above average at the next level. He didn't stand out physically. I think he'll be more of a #2 receiver because he's not particularly big or athletic compared to NFL receivers.
I think Baylor gave up 48 points to Liberty and is the worst team in CFB this year. The Big 12, in general, plays bad defense. OSU has an excellent college QB and enough talent on the outside that they can really stress a defense. My guess is Washington is able to physically beat many of the guys he plays against and Rudolph can get him the ball consistently.
I'm wrong all the time just like anyone who tries to predict how college players will be in the NFL. He didn't display any remarkable traits today. He has before, but I'm skeptical of him. Only time will tell.
