Whenever asked about the RBW fiasco at a public event, Vieira has repeatedly stated that it was a mistake to make the whole team travel NYC->Portland->Toronto->NYC in one week. He says he did it for team cohesiveness but it wore everyone out and in the future he would hold some people back from the travel to have a somewhat more rested squad for the 3rd game in a week like that. This upcoming week has 3 Away games, which complicates things a bit. Instead of just keeping a few players in NYC and not traveling at all, everyone has to go somewhere even if they don't all go to all 3 cities.
PV can take Squad A to Dallas, bring some new players (Squad B) in for RSL, while sending part of Squad A direct to Orlando from Dallas. The Squad B reinforcements presumably go to Orlando since the next game is Atlanta a full week later so what else would they do.
Or he can send Squad A to Dallas and RSL, bringing in Squad B reinforcements straight from NYC for Orlando. Only the first means there are fresh players for each game who did not have to travel to all 3 cities.
I suppose there are other choices but those seem the most likely.
Anyway, figure this into your squad rotation predictions. Probably not everyone who is a potential game day 18 candidate is going to be at all 3 games, and presumably that means some usual starters at least.
