That’s surprising, not only because most key players return from that team, but also because the roster has been bolstered by Julius Thomas (pictured above), Lawrence Timmons and others. Three weeks ago, the MGM Grand and 11 other Nevada casinos set the Dolphins’ over/under for wins at eight. But according to the MGM’s sports book chief, so many people bet the Dolphins would win fewer than eight that Miami’s over/under was reduced to 7 ½. And even now, more money is coming in on the under. A bunch of teams that didn’t make the playoffs last season have higher over/unders, including Tennessee at 9 ½, Arizona and Denver and the Colts at 8 1 /2 and Detroit at eight.
