If you go by the criteria that you should be picking the ones who you think can actually do stuff in the UFC I think Hayder and Seth should have been the picks. Nunez definitely isn't UFC level, I personally like Joe Daddy but I don't think he can compete with either the WWs or LWs of the UFC today, and while Eddie won his season he looked very subpar in the UFC and lost every single fight except for the TUF finale. And of course Mehdi and Lane weren't medically cleared so they couldn't do it.
Hayder made it to the finale and was then cut following his defeat in his very next fight. Usually guys who make it to the finale get more than 1 fight to prove themselves and the guy who beat him (Vicente Luque) seems to be a quiet darkhorse though his nice streak just got ended by Leon Edwards who himself is a great prospect. I think if Hayder can work on his ground game and get some good TDD he could prove himself well in the UFC.
Seth was very hot and cold in the UFC. He got some great wins over Neil Magny and Matt Brown but ran into a wall and compiled a few losses. I think if he can pull himself together and get some good training he could comeback to the UFC and get some more wins, though he isn't the kind of guy who would ever be champion. I don't know what happened to him against Gilbert Smith but I know he is capable of fighting much better than he did in that one.
So while I do like Joe Daddy I think picking him strictly because he had an entertaining fight and didn't get finished was the wrong move especially since Dana specifically said they were looking for guys who could hang in the current UFC. So Seth and Hayder would be my picks.
