That all depends on what you have at tight end. If Reed would be an upgrade then that's probably a better deal. Lynch is just going to be a one year rental, so if you're all in this year that side is certainly better, but if you're looking long term, I could see the Cohen/Trevathan side of things. The thing about linebackers though is that they aren't nearly as difficult to find replacements for as DL and DB's since there are so many good ones that make a lot of tackles.
With your setup Foot, I prefer Cohen and DannyT. Don't trust Reed, surprised he's still active going into week 3 to be honest. And Lynch is nothing special. With your IDP being ILB and OLB specific, suitable linebackers aren't all that easy to find, DannyT has more value than in most standard IDP's.
