Work just beginning for Dolphins DE Dion Jordan

DAVIE, Fla. -- The NFL reinstated Miami Dolphins defensive end Dion Jordan on a conditional basis Friday. Jordan, who missed the first day of training camp, will join the team and continue to be evaluated.

Although this is good news for Jordan -- and possibly the Dolphins -- the work is just beginning for Jordan, a 2013 first-round draft pick.

Jordan has a lot to prove to the Dolphins, both on the field and in the locker room. His coaches and teammates need to know that they can trust him again after two suspensions for violating the NFL's substance abuse policy. Jordan also violated the NFL's policy on performance enhancers in 2014. The harsh truth is he has as many career sacks (three) as league violations (three).

The Dolphins have a new coaching staff under first-year head coach Adam Gase. This could be good news and bad news for Jordan.

On one hand, Jordan will get a fresh start and a fresh set of eyes with a coach he's never played for. On the other hand, Gase had no hand in drafting Jordan three years ago and the level of tolerance could be short.

This training camp is likely Jordan's last chance in Miami. Talent and natural ability have afforded Jordan more opportunities than most players receive in the NFL. But he joins a Dolphins team that is ready to move on quickly if there are any additional transgressions.

The team is deep at defensive end with veterans Cameron Wake, Mario Williams and Andre Branch already in the fold. The team no longer needs Jordan. He is more of a luxury at this point than a necessity.

Jordan trained this offseason in San Francisco and it is in his best interest to be in the best shape of his career. Despite his world of talent, there is no guarantee the former first-round pick will make the final 53-man roster.
