Backup: Tyrod Taylor

Best-case scenario: Pretty Flacco earns every penny of that monster $120.6 million contract by bringing the Ravens back to the Super Bowl for a chance to repeat as champs.
Worst-case scenario: Flacco's contract starts feeling like an albatross when it's mentioned after every game in which he sucksjust like he did in last Thursday's opener in Denver. Well, at least he's always got that awesome T-shirt line to fall back on. Snicker.
