Maybe Watson should've been on the bench 3, I won't mention "unnecessary" (don't want to be over-pedanticWhilst I 100% agree with you on this particularly obnoxious irritant, at the risk of being accused of unneccessary linguistic pedantry are you, yourself, not slightly guilty of a lazy contraction of should have and could have here?
Oh, and PS: Watson COULDN'T OF scored today either, as it 'appens. He weren't even on the bench.
