Whether he was “dishonest” or not depends on the contract. My understanding is they get paid to use the brand stickers, and softs. Is GN different from other sponsors and also contractually obliged players to actually use “made by GN” bats? If so, that would be a bit odd - players source bats from different bat makers and I was under the impression that “sponsorship” just entails using the sponsors stickers. This is why players are always carrying loads of stickers with them.
