On the Casserley stuff don't forget that literally days after he trashed Murray, he trashed Rosen, said he doesn't work hard and he can't connect with teammates, they don't like him because he doesn't work hard. Then Larry Fitzgerald went on with Mina Kimes and said none of it was true, that Josh worked very hard, wanted to get better and was popular among his teammates. I don't know if the Murray stuff is true or not, no idea, but Casserly didn't like either option.
Unrelated but I found it when I googled Casserley, he said the big issue everyone had with Joe Burrow is "he holds the ball way too long. He has to learn not every play is going to be a big one. It's why he didn't play at OSU, when he got to LSU he had NFL caliber Wr's running wide open on a great team and he still took too many hits.If he doesn't learn to check it down and have a clock in his head he's going to find out he won't last in the NFL, he takes too many hits."
So apparently the Burrow taking sacks thing was something that all the scouts forecast coming in.
