The Indiana Pacers opened up their check books this off season by signing Paul George to a big extension, and then bringing in Luis Scola, and sharp shooting reserve guard C.J. Watson
This might explain why they have had to cut corners in other areas of their business because I can't think of another reason why C.J. Watson would find a giant rat (not mouse, rat) in the team's locker room.
Watson posted a pic of the caught rodent with the caption "Rats in the locker room!!! #MasterSplinter #GotEm." Thing's about as big as Master Splinter would be too.
