I think you're better off going with the young guys and people who are kinda hungry over the veteran right now.
If you're signing a veteran to this team, by nature? they're not gonna give a shit. The exception would perhaps be guys like Collins, or the recent signing at Guard, Center.
Victor Cruz would be apathetic about playing with a team with no playoff aspirations and some rookie tossing him the rock. I imagine Kenny Britt feels the same way, and in my opinion..he would be happier on a playoff team.
I think focusing on building through the draft and playing younger guys is the better route. The EXCEPTION again is on the offensive line...something that is a MUST and I value very highly.
Eventually the time will come when the Browns should go free agent shopping for a Victor Cruz type...but the time is not now.
