there is a good reason that he's not rated a top ranked linebacker. probably because he was never really asked to play there.
again, urlacher played safety at new mexico but was still defensive rookie of the year in 2000.
anything is possible.
the kid really seems to have the talent, toughness, and agility to make the switch and of all of the 3-4 olb prospects that i have seen in this draft this kid seems to have the most ability to be an extremely good 4-3 everydown backer.
