Most disappointing Cleveland Browns quarterbacks: 16. Austin Davis (2015)
Austin Davis had himself a nice little run in 2014 when he stepped in and started eight games for the St. Louis Rams. A fairly unknown player, Davis was undrafted out of Southern Mississippi and spent time with the Rams in 2012 and the Miami Dolphins in 2013 before getting his break with St. Louis during his second stint with the team.
In his first appearance that season, Davis was 16-of-23 with no touchdowns but followed that up with an impressive win in Week 2 over Tampa Bay. He then broke out in Week 3 and 5 as he had back-to-back 300-yard passing games.
Davis threw for 327 yards with three touchdowns against Dallas followed up with a 375-yard performance against Philadelphia which also saw him throw three touchdowns. In all, he had 2,001 yards with 12 touchdowns and nine interceptions in eight starts that year.
It was enough to convince the Browns to sign him to a two-year deal in 2015 where he competed with Josh McCown and Johnny Manziel. McCown ended up being the starter but Davis was called into action in Week 12 and led Cleveland to a win.
Davis was then named the starter when McCown was placed on the IR, but he lost that job quickly as he was under center for an embarrassing 37-3 loss to the Bengals. He would end up playing in just three games with two starts (both losses). Davis also completed less than 60 percent of his throws with three interceptions and one touchdown. He was subsequently released and never threw another pass in the regular season for an NFL team.
