One of the biggest surprises in the NFL last season was the Titans’ improbable run to a league-best 13-3 regular-season record and the dethroning of the almighty Colts, snapping Indianapolis’ five-year reign as AFC South champions.

Now, everyone wants to know if the Titans can do it again with Collins at quarterback.
