The thing that bothers me about Jones most is that he's a one read quarterback. He is not good if he's forced to come off his first read. For all the talk of him being some great pocket quarterback, this is what stood out to me. He locks onto a receiver, and luckily for him that receiver is almost always wide open. He's super over rated in the pocket. It's like because he's white and unathletic he's therefore a good pocket passer. He's not. Both Trask and Mond are better in the pocket, better poise, better processing.
I think if you're expecting him to start day 1 you'll be sorely disappointed. His arm strength is fine and his accuracy is great. When everything goes according to plan, he's good in the pocket, good feet, able to navigate. But take away his first read and add pressure and he's a totally different QB.
I like Jones, but it's crazy that anyone can watch him and think he's a top 5 pick. He's got issues. I think he's much closer to Trask/Mond/Mills than Wilson/Lawrence/Fields.
