DeShone doesn't know who he is, so he sends mixed messages. Just look at the last few months. Most kids his age are at the same point in their life, so it's not like he's at a place where you have to be concerned in terms of who he is when comparing him to his peers. However, most his age aren't handed the keys to a franchise with millions of dollars at their disposal.

DeShone needs to do a lot of growing up off the field before he's ready to handle the NFL and all that comes with being a starting quarterback in the NFL.
