I've been contemplating this. I think the approach of 3 mobile attackers cutting lanes can be successful in MLS up to a certain point. What we see in Shaff, Soteldo & Achara is a pretty standard attacking approach in this league. Where it breaks down is when people can't get the ball to that front 3 or teams can't get the counter attacks started.
Nobody is saying we are seeing a Toronto version of the Liverpool attack quality here. What we are seeing is MLS standard attack quality. Can work - doesn't always.
I would say that Shaffs movement has significantly improved & Soteldo quick passing is making a difference & Achara is taking up space he hasn't always occupied causing defences to have to think a bit.
Its good for 2022 but its not "keep Perez" time.
