Potential Reasons for why the Mark Sanchez jersey was behind Manuel

If you watched the Fox postgame show after the Yankees won the World Series tonight, then you probably saw Charlie Manuel being interviewed by Ken Rosenthal. And if you did, then you saw the Mark Sanchez home Jets jersey hanging in the background.
I have no clue what the jersey was doing hanging behind Manuel in what I assume was an area located close to the Phillies locker room, and it is tough for me to definitively say why it was there.
My best guess would be that maybe somebody on the Phillies had an assistant or somebody affiliated with the team go out and get them the jersey before the game, and when they came back they found the clubhouse closed or weren't able to gain access into the locker room, or perhaps it was left by a player as a gift to a reporter or friend. Or perhaps a player on the Yankees bought the jersey for a player on the Phillies as a gift but couldn't find a way to have someone bring it into the locker room for some reason (or maybe he had it intentionally left outside the locker room so as to surprise him after the team headed out of the facility-which would have been a tremendously nice gesture by the way.
There may have also been a player on the Phillies who wanted to change outside the locker room so as to not see the sad looks on his teammates' faces and thus he or a clubhouse assistant brought his clothes outside. This sounds like perhaps the most rational reason for it.
And last but not least, I guess that somebody on the Yankees could have had a clubhouse assistant hang the jersey outside in that area if both team's locker rooms are close to each other or if it just so happened that Manuel was being interviewed away from the Phillies' locker room.
Either way, I am very interested to figure out why the Sanchez jersey was there. It is of no relevance whatsoever, but is a unique sidenote to the close of a great World Series nonetheless, and perhaps even more unique than the funny hat that Phil Jackson wore to celebrate his tenth NBA title last June.
