			I am having a little bit of a tough time seeing how AJ Hawk (and others in similar positions to him) is a match-up LB, but Clay Matthews and Brian Orakpo are LB3+ players.  Perhaps Hawk deserves to be in the match-up group, but I don't see how Orakpo or Matthews are going to consistently generate enough points to be considered LB3+ unless they are in leagues that heavily weight sacks, and even then they are boom/bust players most of the time.
		
		
	 
The LB3+ players are guys I'd have some comfort level starting every week.  If you're using Orakpo or Matthews in a balanced league, they should probably be in your lineup every week.  Too hard to project when either will explode for 6 solos and multiple sacks.  And I'd roster them only if you're comfortable with the boom-bust nature you note -- getting LB1 numbers some weeks and below replacement level numbers in others.  I think Orakpo and Matthews are 9-10 good game, 6-7 poor game players -- my cutoff for an every week LB3.The base defensive ILB (Hawk, etc) are a different breed.  You roster them as your LB4/LB5 and plan to use them only when the matchup suggests a 70% base defense split or better.  Though it may not always play out that way, your chances of guessing right are much higher in this group than the 3-4 OLB pass rushing matchup.
My roster bias is generally to ignore these matchup LB4 altogether unless I'm in a bye week bind during the season.  Then, there's usually a Mario Haggan or Akin Ayodele or the like to be found on most waiver wires.  I'd much rather stash a player with every-down upside (Bishop, Washington, Hawthorne etc last year) if the depth chart cracks than worry over an Andra Davis, AJ Hawk, Takeo Spikes, Dan Connor, etal.
