Weren't they both true SO's? Your implication as "multiple-year guys" seems a bit ingenuine, other than you just don't like them. Just because it's their 2nd year, it doesn't mean they are immediately going to play like a senior or that they have maxed out on their ability.
All that said, I would love a shiny new all-American LB, but I also think the coaches understand the potential of our LB room better than the fans, and it's pretty obvious which position rooms the coaches see as weaknesses. Who knows if it will work out but go ask USC (the real one) or Kentucky or Miami fans how all those shiny new toys worked out for them last year.
