Neither Farmer, Bowen, or Brown is likely to ever be a box linebacker - certainly unlikely that it would ever be their "best position"
And, even at that, that's only 4 LBers
There are very few recruits capable of coming on and playing a significant role at LBer as a TRFR - Poz (even he didn't play until fairly late in his first year) a kid like R Macmillen at OSU......they are pretty rare - - - and, at that, there are a lot more of them than there are JUCOs and GradTransfers who are capable of being a aignificant help
