No. Its completely different than discussing possible rosters. We know which players are on the team, we know which players the staff is recruiting. You can make legitimate speculation out of those two knowns.
The Dude and Mhver3 just make **** up to stroke their egos, and people eat it up. When you're speculating about Big 12 Expansion, at this point there are no knowns. Everything is 100% hypothetical.
If there were supposed "insiders" on this board who were relentlessly spewing complete falsehoods about whether or not a recruit was coming to ISU, people would run them right out for being idiots. Yet in the case of these clowns people find it entertaining.
SwarthmoreCY is correct, and to use your same analogy: We know which teams are in the ACC, we know which teams the conference is recruiting. You can make legitimate speculation out of those two knowns.
We (Big 12) have come perilously close to cratering a couple of different times. ISU was seriously close to being on the horribly bad end of that, out of no fault of our own. While MHV and Dude are throwing a bunch of turds at the wall, a couple have stuck. And realignment continues. It doesn't mean they're always right, anymore than your speculation is always right about who gets a roster-spot. But the ideas they're trolling are thought-provoking. If this **** wasn't important we wouldn't have had a 1000+ page mega-thread about it.
