A few recruiting bits to digest at the end of the day.
Iowa bolstered its rushing attack for the future by landing a commitment from Marcus Coker, a running back from D.C.-area powerhouse DeMatha Catholic. Coker checks in at 6-1 and 225 pounds -- Shonn Greene Jr., anyone? -- and rushed for 19 touchdowns as a junior. There was some buzz back in May that Coker had committed to Minnesota, but he dismissed those rumors. Still, his pledge to archrival Iowa gives Hawkeye fans another reason to gloat.There's a rivalry quietly brewing between Stanford and Northwestern, two academically-oriented schools that chase many of the same recruits. Stanford coach Jim Harbaugh essentially called out Northwestern for its soft scheduling in comments made last month to colleague Bruce Feldman. Don't expect Wildcats head coach Pat Fitzgerald to fire back any time soon, but trust me, there's no love lost between these two staffs. Anyway, Northwestern probably feels a little extra satisfaction about its latest commit, defensive tackle Will Hampton, who decommitted from Stanford last month. Hampton picked Northwestern over Notre Dame and gives the Wildcats another body at defensive tackle.
