I'm saying you're WRONG.
There are players that do posses the DB/LB you say can't be....
Don't believe me, read his scouting report, phrases being thrown around like the BEST COVER LB in the draft, could play SS or LB, FLUID HIPS and EXCELLENT NICKEL LB.

I think a smart DC like Wade could find a way to play him, possibly at SS, or move him around a bit to keep the offense's guessing, even at ILB at times..
I know that sounds extreme to you, or probably impossible in your eyes since: " There is a reason DBs play DB and LBs play LB. And humans just aren't cut out for both."
First, You would have to be able to think outside the box and admit there are players that are LB and DB versitle.
He got to play in the Big 12(pass heavy) his Jr season and Big 10 (run heavy) his senior so he's been exposed to alot of different offenses.
L. David also excels at avoiding blocks and disengaging well off linemen, his burst, explosiveness downhill, and closing speed is all great, which allow him to slip by linemen to get to the ball. Check out this video of him avoiding linemen.

But what I'm most impressed with are his instincts for the ball and his motor. I'll take his speed and desire over typical girth.
As for Ryans, the main reason he was let go was $$, The Texans weren't gonna pay him 6+million this season for a 1 or two down LB. The main reason he wasn't playing the three downs wasn't for him not getting off blocks, he was alwasys more instinctive than physical....it was because he wasn't the same player after coming back from his achilles tear, he was slower, slower to the ball, and had considerably less tackles. 64 combined, 44 solo last year to be exact, compared to 123 combined, 93 solo the year prior to his injury (2009)......so roughly 50%. He almost had the same stats in 2010 playing only 6 than all of last year.
One could argue well thats because he didn't play in nickel situations, but then it goes back to being slower now post injury
and more expensive to keep.
