I've seen this thought, I just don't believe it is the best way forward.
Phil needs to be with his team right now more then ever.
He is currently in the worst form of his outstanding career.
Leaving him to stew in it, while the rest of the boys are playing 1,000 miles away will only be isolating for him in my opinion.
He doesn't need to play a lot in the states, but just the practice sessions and team bonding activities alone will be great to build back up his confidence.
It seems obvious the lad is very down right now, I just personally don't feel like isolation away from the team is the right move to combat that.
