To be fair, TUF 14 was always going to be stacked because it featured basically some of the best 125'ers, 135ers and 145ers in the world who hadnt been in the WEC. So its no surprise guys like Dodson, Dillashaw, Brandao, Bermudez, Brimage, Guadinot and Caraway have done well.
That being said, TUF 12 produced Michael Johnson and Alex Caceras, TUF 13 produced Ferguson and Nijem, TUF 15 (another stacked TUF) produced Chiesa, Al, Jury, Pichel, Cruickshank, James Vick (who is seriously flying under radar but subbed Nijem), TUF 17 has now Kelvin, Uriah, Barnett
