I think you guys are sleeping on the need for another legitimate CM with both Adams and Rzatkowski gone. That might be my #1 priority right now. Even if Casseres makes a huge jump and kills it next year (big assumption), that's still only 2 starting CMs on the entire roster.
while i wouldn't do this I feel fairly confident the team will approach the CM position the same way they approached CB last season. We have a number of young options and they will let them all fight out to play next to Davis. And if none of them look good enough they will acquire someone like they did Parker.
We have a decent amount of work we need to do to the roster though in the next month because of the volume of guys coming back from serious injury that I would not want to rely on with a Plan B. We basically either lost or have recovering from injury 6 of our best 18 players (Valot, Duncan, Beze, Escobar, Adams, Rza)
