Timmons or Butler?

Need to keep one of the two but having a tough time deciding between Timmons or Butler. Who should I keep?

Thanks.

Butler ... chargers offense got hit hard this offseason (lost of their 2 top backs and top WR) ... add in the lost some of their Oline. All that means is their defense IMO will be on the field more and Butler will get more chances to put up more points. (Also he plays the middle, where Timmons could end up on the outside again this year with the injuries at LB)

I think the important thing to point out here is that Butler was only a two-down linebacker last season and still put up respectable numbers and was actually one of the most efficient/effective tacklers in the NFL. Judging my training camp reports and what I've seen so far in preseason, Butler is locked into an every down role this season is a very friendly fantasy position scheme for inside linebackers. He's a good bet for 95-100 solos and top 10 numbers.

Timmons also has a chance at LB1 numbers, but he's a lot more risky.
