Marcus Vick is back on Twitter and bad-mouthing Andy Reid?

Exactly two weeks after he demanded his brother's trade out of Philadelphia, Marcus Vick was on Twitter and off-message Monday morning.

"Yeaaaaa!" the younger brother of Michael Vick wrote Monday morning. "Try everything n your handbook to save your [butt] FATBOY!!!!"

Scholarly analysis of the Vick tweet instantly identified Andy Reid as the possible subject, given the coach's portly frame and recent struggles.

If Marcus did write about Reid, it would go against his older brother's stated wishes. Michael told reporters he said for Marcus to "shut off Twitter" after he went on a Monday night rant on Nov. 5, bashing the Philadelphia Eagles offensive line and criticizing the team's front office.

"You'll never see that again," Michael said two days later. "Trust me."

Who would have thought Marcus Vick wasn't good at heeding calls for discipline? So unlike him.

But maybe we're being too judgmental and Marcus wasn't talking about Reid, but somebody else entirely. Our choices:

1. The little kid from Up.

2. Santa

3. The actual Fat Boys

4. Chris Christie

5. He meant to spell "phat" and was pitching a business plan to Russell Simmons.

Aside from Marcus Vick being awake at 9:15 a.m. to send that tweet, the most surprising thing is that a member of the Vick family doesn't like Andy Reid. The reason Michael can afford to pay for Marcus' cell phone plan is because Reid brought in Vick after his prison sentence and made the decision to get rid of Donovan McNabb and Kevin Kolb. Michael earned the $100 million contract on his own, but it was Reid's trust and guidance that enabled him to do so.
