This is one position on the line that is unsettled and will be an all out open battle between spring and fall. The good news is, lots of guys can fill this role. I expect Hiva Lutui, Jackson Barton, Sam Tevi, Andrew Albers and new comer Darin Paulo to push for this spot. All of them are hungry and all of them are ready to contribute.
Salesi "Leka" Uhatafe will most likely lock this spot up. Last year, as a redshirt freshman, Leka played in all 13 games and his experience will be an asset going into the 2015 campaign.
Siaosi Aiono will be the only senior on the line this year. After moving from right tackle to center last season, he excelled and is a big reason why Utah had so much success during 2014. If senior leadership is needed anywhere on the field, it's right where Siaosi will be. Of all the interchangeable pieces on Utah's Oline, the center spot is not one of them.
Isaac Asiata will move from the right side of the line this season, and he looks to be locked in at the guard spot. However, due to some of the vacancies at right guard and right tackle, Isaac could end up in multiple positions throughout the season. Isaac has been the ultimate utility player; last season he ended up on both sides of the line at tackle and guard. Depending on what happens in the empty spots, we may see more of the same.
The loss of Jeremiah Poutasi may not be as damaging as some would think. While Poutasi was one of the best at his position, he left something to be desired at times. The number one contender to fill this spot is JJ. Dielman. Considered to be the best tackle on the team, JJ should make the transition to the left side flawlessly. I would not be surprised to see Dielman come out of spring as the outright starting left tackle.
The Offensive Line can be a mystery at times. With so many moving parts, the outlook can be muddied. However, Utah has never been in the situation it is currently. The talent at Kyle Whittingham's disposal currently is deeper than it has ever been. The guys currently in this unit are hungry and determined to make a name for themselves. Look for Utah's 2015 O-Line to be one of the strongest units in 2015.
