You're dead wrong.
I still had most of the tapes from the Kubiak era.
KJax was a very versatile DB.
He played mostly RCB at Alabama.
That was where he started out with the Texans.
Quinn played LCB in 2010.
But I think they switch places once in awhile.
I believe it was the plan to utilize KJax' versatility.

Allen came in late during the season and did not start a single game.
In the nickel package, Allen came in to play RCB (the same position he played with the Dolphins)
The Website I mentioned above had most of the info.
I don't remember exactly, but I think both KJax and Quinn had time at nickel, while the other play LCB.
The next year, 2011, the Texans brought in Joseph who also played LCB mostly with the Bengals.
They moved Quinn to safety.
Wade switched the two CBs initially.
KJax moved to LCB, JJo manned RCB.
But after awhile, they became interchangeable.
That year, KJax missed 3 starts and JJo 1 due to health issue.
Allen got the 4 spot starts then.
Again, when all 3 were on the field at the same time; KJax usually was at nickel.
They let Allen walk in 2012.
Kjax remain a versatile player.
He's still listed at LCB and JJo at RCB, but he played everywhere.
There was even one game when the Texans played Detroit; after Calvin Johnson's big first half, KJax asked Wade to let him shadow Johnson.
Wade Agreed, and KJax shut down Megatron in the second half.

Later on, the Texans also have him play at SS and sometimes at FS.
He eventually moved to safety in 2016 but still occasionally played at other positions, a role he continued to play with the Broncos.
