Marcus Jones has the ability to play offense, but I feel his defensive value will be of more use to us.
The same debate was going to happen with Hunter if he had fallen to us. How much to use him on offense and how much on defense, and the answer is he would have been heavily used on one side and only lightly if at all on the other side. NFL requires specialization more than dual threats.
Don't get me wrong, having a Troy Brown who can occasionally play nickel in case of injuries is nice, but that's not the main case usage.
