So much for making the most of a second chance. The Jaguars released defensive end Jeremy Mincey Friday, a transaction that in and of itself wouldn’t attract much notice. But Mincey was effectively on double-secret probation after missing a meeting and being left home from a trip to Houston, so it’s easy to wonder whether he had another distraction crop up. Mincey said the previous punishment was a wake-up call, and after missing two games, he was back in the lineup last week against the Texans. Mincey was one of the last big contracts signed by the previous administration, getting a four-year, $20 million deal in 2012, with $9 million guaranteed.
