You only have to look at 2018's TFC to see what happened to the last BEST ALL TIME MLS TEAM that stood still and ran it back... and that was without losing a NT player of Tyler's caliber.
Renewing contracts, signing draft picks and not getting an impact TAM player at least is a really low bar for "a pretty amazing offseason".
if our age profile wasn't so much younger than Toronto's I would agree with you. We have much better depth than they did though, and have a much younger team. Besides a BWP injury we would be able to withstand a month injury to any starter without the team collapsing. B/B+ grade is fair, amazing maybe not the right word.
