I highly doubt that the tweet was about Shipley being offered what he might perceive to be better terms. I mean, Cov players aren't exactly the most level headed on social media (witness Hickman's fiasco last year), but given how Shipley was in a pretty similar situation (coming off the bench for the most part), I doubt there is any jealousy there. More likely that something with his agent or personal life has pissed him off.
