Sending a seventh-round pick to the Bills for Jones makes sense for the Chargers.
After being drafted by the Bills in the fourth round of the 2016 National Football League draft, Jones only played in a single regular season game, the Bills' final game of the 2016 season against the New York Jets.
Jones received only limited reps with the Bills offense during organized team activities and minicamp this spring.
Jones arrived on the team as an ultra-raw prospect with a strong arm, but little else in the way of accuracy, consistency or pocket awareness.
The trade reunites him with first-year coach Anthony Lynn, who served as the Bills' offensive coordinator for the bulk of Jones' rookie year.
When asked about the trade, Coach Lynn said, "He's the type of QB you want waiting on the runway". "He's going to have the opportunity to come on the field and compete". Jones appeared in only one game for the Bills as a rookie, throwing for 96 yards with an interception in a 30-10 loss to the Jets.
The Chargers worked out former Browns and Redskins quarterback Robert Griffin III on Tuesday, and Los Angeles' coaching staff clearly wanted to bring in some competition for second-string quarterback Kellen Clemens ahead of training camp.
The Buffalo Bills chose to part ways with Jones for what was originally reported as a "late" conditional pick according to NFL Media's Ian Rapoport, who was the first to report on the transaction Wednesday. T.J. Yates signed with the team in April, and Nathan Peterman was later selected by Buffalo in the fifth round. Jones will pick up his development where it left off and have a clear path to being the Chargers' No. 2 quarterback behind Philip Rivers.
