I've a feeling Aaronson might be more likely to lose his place than Roca. We largely play 4-3-3 at the moment. The midfield three would be Roca holding and Adams and McKennie in the engine room outworking the opposition. That would supply the front three with enough ammunition to get at teams and hopefully protect the defence from being overrun. I'd like to see Roca sit even deeper and make a back 3 when the full backs push on in possession. A bit like Phillips did. One of Roca's faults is he sometimes gets caught a bit too far up the pitch. But basically McKennie could take either Roca or Aaronson/Harrison place depending on formation.
Full backs are the wide roles but certainly Gnonto and Summerville (before his injury) provided good width on both sides. We have plenty of width. It's a myth that we don’t tbh.
He has his uses although it depends which format your friend Jesse wants to play, he (Jesse) does have a format and knows what he’s doing I assume although I was always told never assume
