Muyl is a better wingback than attacking player.
Whether Adams wants to be a 6 or 8, he wants to play centrally, not as fullback or wingback.
Veron doesn't do great when he needs as the second forward or as a 10, but as winger, when all he needs to do is run, cross, take guys on 1v1, press, he's fine. He's had more success as a line forward, but he's better than the Muyl, Grella, etc. at wing right now.
Again, I just hate Muyl defensively. And pretty much offensively so I'm hard pressed to say he's good at anything outside of hustle. Hoping he develops better touch going forward and hopefully better instincts defensively. He's not very athletic despite the hustle so he'll need those qualities.
And why even bring up Grella when he's not a factor? I know you're not a fan but there are no more worries about him playing this season. And when Royer is healthy, Muyl won't even be worth discussing.
Overall, there is no winger position in this formation outside of the wing backs. The only guys running into a lot of 1v1 situations are Adams and Muyl when Muyl plays there. The old wing positions are pushed too far inside to have that happen nearly as much. The other thing is that Veron's confidence right now is as high as it's ever been. You trot him out there at one of those offensive mid positions and he doesn't do well, that confidence drops. And in the playoffs, we need him in his current role. Not as an offensive mid spot. Davis and Royer will be at those positions and they should be.
