OLB Koa Misi – Second round (40th overall)

Misi’s versatility makes him (on paper) the ideal complement to Cameron Wake, who appears to be the team’s new pass rushing specialist. But considering most NFL insiders say it generally takes two years to learn all the aspects of being a hybrid linebacker in a 3-4 scheme, Misi might have a ways to go before his knowledge base catches up to Charlie Anderson, who has been working in this system for two seasons, and at times flashed when given opportunity. But considering Anderson is a free agent next offseason the Trifecta would rather invest in Misi than Anderson if their contribution level is even close to even during training camp and the exhibition season.

I don't buy into the 2 year thing. Depends on the people involved. With the right people a transition can be fast and painless.

I'd say several years is fairly accurate ... for a great rookie to become a great player ... or good to good.

Depends on the target outcome you're looking for.
They may play & even do well the first year or two ... but I think they're talking about playing at a level to influence the game.
