Love the site! - some advice?

I love what you're doing helping all of us idp novices!  This is my first year of a dynasty league with 3 starting idp flex spots can be any position. Scoring is as follows:

Sack - 4
Interception - 3
Fumble Recovered - 3  
Fumble Forced - 3
Safety - 2  
Solo Tackles - 1
Passes Defensed - 1  

Currently on my roster I have Poz #63 LB, J. Anderson #1LB, Timmons #4 LB, Vilma #23 LB, and LaRon Landry #3 S.  

My question is : Should I replace any of these players with any of the following ww pickups?  

Laurinaitis #18 LB, Rocky McIntosh #14, Derrick Johnson #32 LB, Chad Greenway #32 LB

Again, really enjoy listening to your podcast as well!  Keep up the great work!

I would drop Vilma for Laurinaitis. He's still on pace for 100 solos this year and is a very safe option. Vilma is as well, but I see Laurinaitis as a slight upgrade. Anderson is just too hot to drop right now. He's pace will eventually slow down and he will return down to earth. But he should still be a good LB2 moving forward.
