Lightning-rod wide receiver Santonio Holmes, who spent last week with New York Jets teammates Mark Sanchez and Tim Tebow at Sanchez's "Jets West" passing camp in California, said Monday night he doesn't think a two-quarterback system can succeed in the NFL. But he believes the Sanchez-Tebow dynamic can work because it will be scripted, with Tebow operating from a specific set of plays -- or so the Jets claim. Without that, Holmes suggested, it could pose a problem for Sanchez.
