Why did the Nets fire Byron Scott?
Even though he led them to two NBA finals, I don't think things were working out so well between Kidd and him. They fired him for problems he was causing the team.
There is no one called Byron-strength, but there is a gym leader called Byron. He is the 6th gym leader and is in Canalave City. He uses steel Pokemon so I recommend you to use water or fire. Byron will give you the ability to use strength and he will also give you a TM (I'm not sure what TM it is but it is a fire one).
