Dion Sims Back in the day, before the time of Dan Marino and David Woodley was trying to take the Dolphins to the promised land, names like Joe Rose, Jim Jensen and Bruce Hardy were commonplace.

Those players, along with the likes of Duriel Harris, Nat Moore and others did not strike fear in the opposing secondary.

Thank goodness the Dolphins had an outstanding defense under Bill Arnsparger and the famous “zone blitz.”

It is also a good thing general manager Bobby Bethard knew how to draft players out of nowhere and make them fit into what Don Shula and his staff had in mind.

Today’s Dolphins are a lot different than the one displayed some 35 years ago. Like all teams, decades of development and technology has led to a completely different NFL.

With players who are bigger, stronger and faster, there is more chance of injury and a career ending with one hit. The “Not for Long” league could also be the “one and done” league as well.

When the Dolphins received word that tight end, and major free agent signee, Dustin Keller was done for the season with a knee injury (a nasty dislocation), it put more emphasis on how the Dolphins used to be and how no-name players worked in the past for this organization and how they will have to do the same for this team in 2013.

In other words, the names Charles Clay, Michael Egnew and Kyle Miller or Dion Sims are going to be the most popular names on the team the next few weeks. Finding a player on the waiver wire may help or a last minute trade could make a huge impact on the team, but I do not see that happening anytime soon.

What the Dolphins have on their roster are the players offensive coordinator Mike Sherman is going to have to make work. And it can be done.

According to a report on profootballtalk.com, “The Dolphins have placed tight end Dustin Keller on injured reserve after he suffered multiple right knee injuries in Saturday’s exhibition game at Houston.”

This was a move we all knew was coming. The article also stated that Keller tore the ACL, MCL, PCL and dislocated his knee all in the same hit by rookie defensive back DJ Swearinger. Keller, who only signed a one-year deal with the Fins, will miss the 2013 season and whether he misses more time will be determined later down the road.

The Dolphins' offense had begun to show life in the preseason. Lamar Miller has shown flashes of brilliance in the running game. Mike Wallace and Ryan Tannehill have been working on timing and route running. The defense has been playing well and the front four could be the best in football this season. The team was and is moving forward. This team lost a key component on their offense. But if they are going to be a contender, like all good teams, they will need to find a way round it.
