Call me crazy but I don't think we really need any of those attacking midfield positions. Ivan looks good, Omir looks good, and you have both Royer and Muyl. Kaku is very good at his spot.
We need CB depth and LB depth. I could understand the argument for a true 6 because we don't really have one. Also understand striker as well and that's the spot that will cost.
We're still in a spot where we've got a dozen decent right wingers, but no great ones. I'd be 100% on board for what defendyourself said earlier in the thread, sign a legit starting right winger and trade anyone not named Omir for some more defensive depth.
