The Rangers left for Tampa after the game last night. Richards is a wine collector. Someone tapped into their supply it seems. Richards has a wine cellar in his TB home. He discussed in May when he was at the NHL store.
I was going to post it, but I checked this morning and he deleted it.
Therefore my theory:
Gaborik was wasted and sad about the game. He gave Pamela a little tweet. In the morning he realized what he did and deleted it.
