USA is the biggest looser of postponing OGs. Despite they lost only one player from starting 6, a lot of problems appeared in the team - Anderson with a few months break, Sander recovered from one injury and got another, Jaeschke the same, Defalco was under a big pressure and he just didn't get it by. To many too unexperienced players appeared in the team and taking VNL result, it's not a surprise.
If not a postponement, they would play in 2020 without Sander, he wasn't ready to play until December, and DeFalco would have one year less experience, when he made a leap in 2nd part of this year's season. Anderson and Holt could be in a better shape after a season in Modena, but I don't think they would compete for a medal either.
I'm not a fan of Speraw, but it's not his fault Anderson took a year off, Sander looks to be past prime, Russell is out, Holt is 34yo and had pretty bad club season in Monza. He gave a chance to young players during a VNL, and only DeFalco delivered some solid level. Maybe a next year they will be able to regroup and convince these old guys not to retire, and win some last medal under the same scheme.
