The problem is we don't see what goes on behind the scenes.
If he trainers tell Byron his legs aren't there to play the OF but can still hit, who are you blaming?
If Buck is killing the ball in practice and in the cages and the staff and manager feels he is an asset to the team... then what?
It's really easy for fans to say, "Psssh 0-4!! He's a POS, put him on the IL! He can't play OF, then he can't hit!"
You really think that Rocco knows he's injured and struggling, but keeps him batting third and risking his job because of Buxton's pay escalators?
