Zach Brown at strong is not better than a healthy Koa Misi. I prefer neither, but I rather gamble on Misi knowing he'll likely take a paycut and is a better fit than guarantee a bunch of money to Brown to be a bad fit on defense.
strong- Timmons
middle- Kiko
weak- Brown
bam. Brown would be better in the middle or weakside. Not sure why we would go against the logical thing and not put Timmons in misi's spot
