I think you are understating just how incompetent Khiry is. Does Brooks Lennon make Khiry money? He's at least competent.Stertzer is worth discussing. He is the only NYCFC player in our short history that has gotten subbed into then subbed out of a game. The dude needs to go away right the hell now.
Shelton, is the kind of player a GM needs to trade out for the coach's own good.
RJ Allen I'm kinda torn with. Yes he's expensive, but we're getting so much TAM next year that he might be worth keeping around as deep depth. But that's just me being sentimental on someone who was here for round one. The smart move is probably to sell him.
But again we get to the larger overall point you alluded to. Once you get past the XI in MLS you're going to need to pay guys like 100k a year or less. You need people who can suck on a small salary, but not suck too much. Khiry for all his faults is at least a non entity when he gets on the field, if you compare that to some of the other dumpster fire's in the league who occupy his salary position on a roster, he isn't that bad. I just personally think PV is more enamored with Khiry's physicality than is probably healthy, but thats a secondary issue.
(He makes 53k, looked it up.)
