According to Pittsburgh coach Mike Tomlin, the 3-4 hybrid "rush" linebacker is the most difficult position to scout and one that everyone is looking for.
Pittsburgh coach Mike Tomlin said, "I think the outside linebackers, the hybrids, are the most difficult guys to evaluate and draft because what you're looking at and what you're asking them to do is two different things."
The article goes on to say that patience is also a requirement when drafting the 3-4 hybrid LB. Examples of LB's that took time to develop include Adalius Thomas when he started with the Ravens, Mike Vrabel who started in Pitt but didn't succeed until NE, Jarret Johnson with the Ravens, James Harrison and several others.
"You're going to have to have a lot of patience with these guys as they develop," said Kevin Colbert, Pittsburgh's director of football operations. "Everyone who has been in our system as outside linebackers, it usually took them a minimum of two years and usually three to four years before they were ready to contribute, and a lot of those guys contributed a heckuva lot as they turned into starters."
This statement seems to me a great indication of why it was so important for the Chiefs to get Vrabel and why Aaron Curry won't be the first pick. Especially, since we need our top pick to produce right away.
