While a front office should be in tune with the fan base (they are the one's buying tickets and merchandise), personnel decisions should not be made based on comments on social media. Baseball is too cyclical, players have terrible stretches followed by hot stretches, to base decisions on fanbase (over)reactions.
As far as Pagan is concerned, if the team had received a viable trade offer, I believe they would have pulled the trigger. Just because rumors state that a player is in other teams radars because of peripherals, doesn't mean that an offer, or at least a reasonable offer, was tendered. And let's be real here, he never stood a chance here because of the fanbase's love for Rogers (who once again is performing terribly). Pagan's numbers (results and peripheral) are the same or better than Jax's numbers and the fanbase loves Jax.
I believe we will see Lewis in early June when either his performance dictates it or injury forces it. But let's not be too upset when Rocco sticks him in CF again, its going to happen.
