My theory is 247 is in Nashville and will simply happen to hear about TN kids by chance early on and rank them when hardly anyone is ranked, so they appear higher. Then drop when national kids all start coming in to their view.
Seems like this staff is trying to get more involved in the Mid Atlantic and North East also. I think that having Osovet on the road will help us get more into DMV, Pennsylvania, and NJ. I think it makes sense because we can sell the closest school in the best conference.
FWIW, 247's composite rankings list 11 4-star prospects in TN with Pennington just 7th; looks like he's dragged down by Rivals' ranking of him as the 10th-best instate prospect. And while 247's composite ranks only 4 Tennessee guys in the top 200, another 12 are ranked in the top 500 so it looks like there are quite a few 3-stars who could easily reach 4-star status.
