A franchise quarterback playing under his rookie contract is the NFL's most precious commodity. He's a one-man solution to the two biggest problems facing every team: how to acquire a franchise quarterback (he's already here!) and how to build around him (he's on a cheap deal, so we can pay other guys!)
Teams with good young quarterbacks often fast-track their Super Bowl timetables to strike before that rookie contract expires and the bill for quality quarterbacking comes due. That's why the Eagles were so daring in their trades and signings last year (and remain aggressive this offseason) and the Rams are assembling a Suicide Squad on defense.
