We are off to a good start with in state players. There will be an ongoing debate on who is the best player in the state between Barton and Mone(committed to Michigan). From my POV, if I had to choose between the two, I would choose Barton every day of the week and twice on Saturday. Now that is not a knock on Mone at all as he is an outstanding player in his own right, but I look at it as a "value over replacement" discussion.
Utah has had good luck with DT's, finding hidden gems and developing some existing "Stars" into first round draft picks. So even if they ultimately cannot sway Mone out of his Michigan committment, we are very likely to find a very good DT and have them excel in our system. You could say that we already have proven this with Havili.
Offensive tackle, on the other hand, is as high a premium position as quarterback. It is shown in the NFL as well as college. Teams covet elite OT's at almost the same level that they do quarterbacks. The ability to take a B or B+ tackle and turning them into a high NFL draft pick is nowhere near as easy as it can be at other positions. This is mostly because the physical attributes of an elite OT are very hard to come by. You must be tall, big, but have great flexibilty and the feet of a ballerina. Compare this to say, RB, where you find almost every variance in height, weight, speed, etc imaginable, and can still have a very effective product.
I look at Jackson as the most valuable recruit that Utah has landed since I started following recruiting(2007).
