It's between junior middle and welter for me. 154: Boots, Vergil, Fundora, Josh Kelly, Madrimov, Bakhram. 147: Ryan, Teo, Devin, Caterall, Hitchins, Keyshawn (potentially), Paro, Norman, Paddy Donovan
Light heavyweight is loaded with talent, but too few interesting matchups are being made. 140 has a lot of good fighters at the present time, I imagine most of them will eventually move up to welterweight. Heavyweight could be very good, but the better up-and-comers like Jalolov have been ruined by inactivity, while some mediocre fighters are given many opportunities simply because they are British.
