Pete Carroll put the world on notice last week that the " comp was on " at right tackle in Seattle with former starting left tackle George Fant officially switching sides to push thus far disappointing 2016 first round pick Germain Ifedi.

Friday night ' s preseason matchup with the Minnesota Vikings and their vaunted defense provided the perfect opportunity to evaluate both with Ifedi starting all but one series at right tackle in the first half and Fant getting the rest of the action.

Overall, the play from both was very encouraging.

Ifedi mostly matched up against 12-year veteran edge rusher Bryan Robison but also saw time against former Seahawk defensive tackle Sheldon Richardson. Some of Ifedi ' s best blocks came at the second level, including when he met up with Pro Bowl outside linebacker Anthony Barr to provide the clean middle Chris Carson zipped through for the Seahawks first touchdown of the game.

He was also effective at the line of scrimmage, creating a push here against Robison.

While lighter on his feet than most give him credit for, Ifedi certainly has struggled with speed rushers over the first two seasons of his NFL career, which is why the Seahawks are wise to be considering their options with Von Miller, Bradley Chubb and the Denver Broncos ' fierce pass rush looming in the regular season opener in a couple weeks.

Robison got the better of Ifedi on this snap, which easily could have resulted in a holding penalty.

Perhaps because Ifedi otherwise played pretty clean in this game he got away with it, likely solidifying his grip on the starting role despite an exciting debut at right tackle by Fant.

It is worth noting that much of Fant ' s time on the field was spent against players not as established in the NFL as the starters (and in some cases, stars) Ifedi played against, squaring off against much younger players like Stephen Weatherly, Jaleel Johnson and Tashawn Bower.

Lesser competition, however, does not take away from the impressive consistency and physicality Fant demonstrated Friday night.

Fant has really transformed his body since signing with the Seahawks as a former basketball player at Western Kentucky. His core strength and flexibility are demonstrated by his ability to anchor against this bull rush and his iron-like grip showed up when moving defenders in the running game, as well.

Or simply just toss defenders to the ground, as he did here with Weatherly, a 6-5, 265 pound third year pro out of Vanderbilt.

Though Fant did not have a truly ugly snap, he wasn ' t perfect.

Fant was flagged for a false start and could have been penalized a second time but Seahawks guard Willie Beaver was instead blamed.

Fant ' s worst snap was probably this one, though he battled gamely to recover just long enough to give Alex McGough (who also had an encouraging game) time to deliver the pass.

As expected, Fant was not quite as effective in creating movement at the point of attack in the running game as Ifedi but he was already more consistent in pass protection.

Put simply, Ifedi needed a strong performance against the Vikings and he delivered it, but Fant may have gained on him anyway.

Their encouraging play certainly creates plenty of intrigue in next week ' s preseason finale against the Raiders, whose rookie duo of Arden Key and Maurice Hurst, Jr. is generating almost as much buzz as Seattle ' s flashy first-year defensive linemen Rasheem Green, Poona Ford and Jacob Martin.
