I agree that you have to recruit on potential and it takes time to develop good O-linemen. I'm not saying this guy couldn't be good, he could turn out to be great. I like how well he moves and he seems to be really aggressive.
My point is we have plenty of potential already on the roster. We will have 16 offensive linemen on scholarship next year, 10 of which are underclassmen. These guys were no schmucks coming out of high school. There are players already here, and they need to be developed. We can't overload one position at the expense of others.
I think the staff will take the spring to see what they have, set their goals for roster balancing, and then start addressing position needs in the 2019 class.
Based on percentages, you should have 17-19 scholarship O linemen, so we are not overloaded. I look to the junior class as to what the recruiting class should be replacing as far as depth. That class has 3 (Barnett, Gaylord, and Decker). In addition, the sophomore class has 5, so you will be losing 8 in a two year period. Thus, taking 3 this year and 4 the next two years would kind of even that out from a roster management perspective. They could also fill any hole(s) in OL for this class with JUCO recruit(s) next year or the year after.
