I don't get why Maatta always gets mentioned in this context. He's the only guy out of that group (Holl, Ghost, Chiarot, Petry) that should be kept, imo. He should rather be extended, at that salary he gets this season. The other 4 guys are all getting more money, which is just hilarious.
He's so defensively sound, makes so few mistakes - it's not by accident that he leads the team in plus/minus. Same story as Ras, for example. Yes, a few brainfarts here and there, that drive you nuts and kinda distort the overall impression - but that's the kind of players you want on a playoff team.
Ghost meanwhile.. he is like walking towards a house and when you are close enough you realize, you're in a movie setting. That it is just a front, and no real house behind. I'd sell the guy at the deadline if I were SY.
Put Mo on PP1, Walman on PP2 (or the other way around, whichever works better), move Ed up and be better overall.
Plus, right now, we are at a point where we probably shouldn't just sell for a pick. Rather take Ghost + prospect(s) + pick(s) to get a real upgrade on D.
