I'm not really concerned about this kid's future position. He has a big frame and he's an athlete, he could end up just about anywhere. If he isn't able to add weight an maintain athleticism, I expect to see him at WR or LB. If he is able, he'll play TE or DE. I don't think the staff knows or particularly cares. They have a general idea and go from there. My guess is that they see Elmore as a TE (most likely), Lingen as a guy who will play TE but could grow into an OL and Gibson as an OLB and possible TE. At the end of the day, these guys appear to be 3 good football players who will help the program. We are fortunate enough not to have to worry about any position that is incredibly thin and we can recruit some guys who are just good athletes.
On a side note, Wedley Estime changed his name to Dadi Nicholas and he plays quite a bit for Va Tech. He is in their rotation of DEs and he will compete to start next season (his JR season).
