The Jaguars acquired Albert in a trade with the Miami Dolphins back in March. The Jaguars traded away a conditional seventh round pick in the 2018 draft if Albert made the Jags final roster. Since Albert did not make the roster the Jaguars will get their pick back.
When Jacksonville traded for Albert it was assumed that he would be their starting left tackle for the 2017 season. In April the Jaguars draft OT Cam Robinson from the University of Alabama to presumably be their LT of the future. I believe this is when Albert knew the writing was on the wall that his time with the Jaguars may be short, and he requested a new contract to obtain some of his money up front.
