The fourth part in Miami Dolphin Nation's training camp preview takes a look at the offensive line. I will spare you of the lag of analyzing every position on the O-line. I know that talk about any position on the offensive line is not as exciting as that of the receivers, running backs, and quarterbacks, but the O-line is just as important. After all what where did Bill Parcells and staff turn to to start the re-building process a year ago. Miami went with Jake Long a left-tackle. They went and got protection for the quarterbacks blind side even before they went after a franchise QB. This unit as whole had a very solid year last year protecting Pennington very well all year long and spurring a solid unconventional running attack. However, the one place this unit performed sub-par would be running the ball out of base formations. If you think about how they had some success running, like the wildcat formation (even though people who think this was Miami's main source of offense because of all the high-lights are mistaken, with the Dolphins only really running it about 5 times a game after its huge success against the Pats) and other ways of trying to find some room like handing it to a man motion, faking the pitch and handing off up the gut, and reverse plays. The Dolphins were never able to just drop back and pound away at teams. Teams that had dominate running attacks like the Steelers, Titans, and Panthers didn't need any trickery to run all over opposing defenses. Not trying to dis the wildcat of course, because we all love it. I am just pointing out an area that needed some improvement because if you get satisfied and complacent and don't look at ways to improve then you will not stay atop the division for long. Bill Parcells and Jeff Ireland obviously had the same thing in mind when they signed Jake Grove and Joe Berger this off-season. Maybe some of the problem with not being able to run out of base formations has to do with Chad Pennington being the quarterback and teams being able to stack guys in the box, but the offense line additions made this off-season should improve the running attack whether its the wildcat or the regular old single back formation. Projected Depth Chart: Offensive Tackles Starters: LT Jake Long: The Dolphins got exactly what the wanted last season; the anchor for this offensive line that will be there for the next ten plus seasons and he was no bust in his rookie season making the pro bowl. Long became the first number one overall pick to make the pro bowl in his rookie season since 1981. He protected Chad Pennington's blind side well all season long, only giving up 2.5 sacks in his rookie campaign. Expect Jake to continue be the dominate force on this offensive line for years to come. RT Vernon Carey: It was a concern headed into the off-season if the Dolphins were going to be able to bring Carey back. However, Miami solidified their right tackle position for the next six years signing Carey to a 6 year 42 milion dollar deal. Carey who was born and raised in Miami and played his college ball for the Hurricanes likely will be able to end his career for his hometown team. Guards Starters: LG Justin Smiley: Was playing very well as the starter in '08, but went down in the St. Louis game with a broken leg. It was never really a question could he have his job back as long he was healthy. Smiley says he is 100 percent and took most of the first-team snaps in the OTA's. RG Shawn Murphy: This is probably the only real uncertain on this line. Donald Thomas was going to be the starter here last year before he broke his foot and was going to be the starter again this year but tore his pectoral muscle this off-season and will miss a good portion of camp. Murphy has the role for now and will keep it with a solid camp and pre-season. Last season's starter Ike Ndukwe will have something to say about this however, and could turn it into an intriguing position battle. Center C Jake Grove: The center position was the position that needed the most improvement on this offensive line, and that's exactly what the Dolphins did bringing in Jake Grove from the Oakland Raiders. Last years starter, Samson Satale, got pushed around at times by bigger nose-tackles. The 6-4 300 pound Grove should put an end to that and if this running game has great improvement this acquisition will get a lot of the credit.
