Given how every single team is shamelessly trying to pay as little as possible, I think you're vastly overstating how unusual it is for none of these guys to be signed as of 1/8. The blessing/curse of advanced analytics is that there is now a ton of available data to convince owners/GM’s that these players are (sometimes) not worth what they’re asking
Well that one the guy got hurt on the play. Based on no contact and how long he's stayed down, might be either Achillies or knee. He didn't roll the ankle so it's not that. True, but then there were no other safeties anywhere close
I'm not ready to say Mitch isn't the guy, but for every awesome throw he had an equally awful one. He greatly benefitted from Allen Robinson's ability to catch anything within 10 feet of him
