Denver Broncos quarterback Peyton Manning will play at least two more seasons in the NFL, according to ESPN's Chris Mortensen. Responding to a question on Twitter, Mortensen said that Manning will play "at least two more years, maybe more." At this time last season, many were still doubting Manning's ability to come back and play another down in the NFL, let alone another season. Manning was coming off multiple neck injuries and subsequent surgeries, and the reports ranged from, "he's retiring tomorrow" to, "he'll play but don't expect anything more than five-yard passes." Few seriously predicted he'd return to form, but return he did. Manning's 15th season was among his best. Under Manning, the Broncos went 13-3 and had the No. 5 passing offense in the NFL at 283.4 passing yards per game. At this point, it's hard to imagine Manning having a down season for any reason other than his body letting him down.
