I also wonder where all the Jones love comes from, but I have to be honest, I never watched him play. I will say this, I watched the NFL network show that this mock was released in. Mayock really made a convincing case for this kid and says in three years he thinks he will be one of, if not THE best D-Lineman in the league. That's pretty high praise from a guy that I consider to be a pretty good evaluator of talent, at least among the talking heads that we all watch.
At the very least, I feel alright with the pick if we go there. I would still like to have DeCastro if he's there, but again, I'm showing my O-Line bias. The reality is, if Jones is/will be that good then he would be a far more valuable pick than any O-Linemen save for a lock down LT.
My problem with him is that just like like Coples, Jones is mostly talked about as having a lot of potential. We don't really know what he can do. With Mercilus, we do know. We need someone to come in right now and produce right away, and I think the most likely DE to do that will be Mercilus.
