Hey Ian,You talk about recruiting rankings in that article a bit. I am employing the 3 level approach in looking at how teams are recruiting: talent, fit, and number.To wit, OU took ONE defensive lineman in 2016 (a DE), and again has only one DE in this class so far. That's ZERO DT's in 2016 and 2017 (to date). Only at the elite level (top 2-3 at each position in each class at best) is there a sufficient difference to warrant comment. For OL, I don't think there is really utility for 4-5* because of the vagaries weight gain, development, and motivation. The key factor is getting a number of players at each position with comparable capability. This does two things: provides depth in a sport with known injury potential, and provides competition. Alabama and Ohio St (and soon Michigan) are soon going to dominate because they bring in talented freshmen at each position every year to push incumbents.
