Giants Claim QB Cooper Rush from Dallas

The Giants have claimed 26 year old QB Cooper Rush off waivers from the Cowboys.  They cut Reggie White Jr. (Not that Reggie White) and Alex Tanney must be packing light. Rush spent the last 3 years in Garrett's Cowboy offense after leading a surprising and fun Central Michigan team. He knows the O and can presumably help install it. Now what's Tanney's job? Exactly.
