The Jaguars can move Walker Little at right guard, bench rookie Anton Harrison
This would be a short-term solution. So far, rookie Anton Harrison isn't off to a great start to his NFL career. The Oklahoma product has given up three sacks in two games and has struggled in the running game. Once Cam Robinson returns, the Jaguars could move Walker Little to right tackle.
As previously stated, Little has experience lining up at right tackle. He took things to the wire. In the end, Taylor had the edge because he had played the position longer and it's fair to assume Little would've seized the job if he had had more time to prepare.
So let's say the Jaguars move Little to right tackle, they would then have to bench Harrison. This would give the offensive line an immediate boost but might not be the best strategy in the long run. Leaving aside the fact that it could have an effect on Harrison's confidence, the only way he's going to get better is by playing. There's only so much he can get from watching from the sidelines.
The Jaguars could reinsert Harrison back into the lineup next year but that could potentially slow down his development. Keep in mind that the Jaguars invested a first-round pick on him expecting him to be Jawaan Taylor's immediate replacement, so it wouldn't make sense to keep him on the sidelines.
