Michigan may have helped. They may not have helped. One thing is for certain - the media is latched on to the Wolverines like ticks chowing down on a animal, and they aren't going to let go until they've sucked every drop of blood they can out of the story. If there's any proof that Stallions or his enterprise sent stuff to teams out of conference, that's huge news, and it'll leak. Sooner or later, it'll leak, and we'll know. My advice would be to wait, enjoy the circus being in Ann Arbor rather than Knoxville, (as it so often seems to be), and let the bloodsuckers do their dirty work.
Not that I'm lecturing people who want to speculate. Hell, I'm speculating online about it too. The wristbands, the bizarre way in which a terrible South Carolina suddenly demolished UT and Clemson in back to back weeks, the idea that this dude and his posse worked to manipulate the entire sport to the benefit of Michigan, it'd be one hell of a story if it's true.
