Landry Jones wasn't signed by Oakland to help add depth to their quarterback position. On Wednesday, shortly after he was released by the Raiders, Vic Tafur of The Athletic revealed why Oakland had signed Jones in the first place.

Landry Jones has served his purpose and his time with #Raiders is up, sadly. Former Steelers QB was brought in to help develop playbook for Antonio Brown, and Landry was released Wednesday to make room for TE Erik Swoope. — Vic Tafur (@VicTafur) May 22, 2019

If this is true, and if Jones didn't know about this arrangement prior to signing with Oakland, this is a pretty bad look for Raiders head coach Jon Gruden, who essentially wasted Jones' time while playing tutor for someone he would never have the opportunity to throw passes to. Instead of possibly landing on a team that would have given him a chance to compete for a spot on the 53- man roster, Jones instead spent the past eight weeks on a team that had zero intention of keeping him.

Pittsburgh's fourth round pick in the 2013 NFL Draft, Jones will now return to the open market as he looks for his next opportunity. Jones, about a month before being released by the Steelers, spoke with 247Sports during Pittsburgh's 2018 training camp. Jones spent three weeks with the Jaguars last season before signing with the Raiders back in March.

Ben Roethlisberger, like many members of Steeler Nation, was surprised when Jones was being released by the Steelers just before the start of the 2018 season. Instead of keeping Jones, the Steelers opted to promote second year quarterback Josh Dobbs to No. 2 on Pittsburgh's quarterback depth chart. Rookie Mason Rudolph spent the year as Pittsburgh's No. 3 quarterback.

"Kind of shocking, but I understand what they did that," Big Ben said of Pittsburgh's decision to part with Jones. “He was so valuable to me when I came off the field. I trusted what he told me, and that meant a lot. Charlie Batch, Byron Leftwich, Bruce Gradkowski. I put him in that category."

When asked why the Steelers went with Dobbs over Jones, Pittsburgh head coach Mike Tomlin said that it was more of what Dobbs did -- as opposed to what Jones didn't do -- that got Dobbs the job as Pittsburgh's No. 2 quarterback.

"It was a very difficult decision," Tomlin said of the decision to part with Jones. "A lot of them were difficult ones. And I think that speaks to the process in that we had a good 90. Josh was presented very tangible challenges, and we feel like he met those challenges. We expect a lot from second year players, in terms of growth and development. You can say the same about Josh Dobbs."
