Thats would be a simpler explanation for the sudden change to negotiate a plea.
Ok, I'll bite. Who's Marcus and why would including him in the supplemental indictment be a reason for Vick to enter a plea?
Michael Vick has a younger brother Marcus, who also played QB for Va Tech but was kicked off the team for disciplinary reasons following his junior season. He had a couple of run-ins with the law while at Tech, and another after he was dismissed. He tried to catch on last year, unsuccessfully, with the Dolphins as a receiver.
