I don't think giving Lineker anyone near the top of the division is right until he shows he can make weight consistantly.
The guy has missed weight by a fair margin 3 times now in the UFC. Either he needs to figure out how to make and stay on weight, move up to BW, or he's going to see his UFC career over when they cut him for repeatedly missing weight.
Being entertaining is great and Lineker is entertaining I love watching him fight but he's unprofessional as hell missing weight so often and the UFC doesn't take that lightly.
