20. Denver Broncos
Joe Flacco, we hardly knew ya. The Super Bowl-winning quarterback with the Ravens had a short, injury-riddled run in Denver. That opened the door for Drew Lock to impress at the end of the season. The Missouri product heads into his second season and if continues to show the kind of play he did in going 4-1 as a starter, Denver would be in strong shape. The backups are Brett Rypien, Jeff Driskel and Brandon Allen. John Elway has to hope Lock is the answer.
