Starling gives him a boxing lesson. Porter smothers his own work. Moochie blocks most of his punches.
Good fight! Shawn outworks him for a few rounds, but Starling’s sharpshooting swells him up and on the way to a UD.
The speed of Porter would show early, but Starling's defense and being just a better fighter and natural bigger would cause an easy UD.
Gotta go with Moochie here. Coasts to a UD without much trouble — maybe loses a round here or there but Shawn doesn’t have enough offense to overcome Moochie’s peek-a-boo and countering. There are some better offensive fighters who would be too much for Starling, like Oscar or Shane Mosley, but Porter isn’t one of them.
