The moves with Gray and Jackson are neither for rebuilding or competitive, that's the problem. And it shows how there is no change, they value the fringe players or over their own prospects. Gray has no business being on a major league roster and shouldn't be recalled. The only role Jackson should have is backup catcher and that role is currently being filled by Caratini.
They are making these moves because they think it makes them competitive. I don't know what more evidence Tom P. needs but Zoll should be fired today, not the end of the season.
