This according to Marlins general manager Michael Hill. From Joe Frisaro at MLB.com:
Appearing as a guest on Marlins flagship station 790 The Ticket’s “Hot Stove Show” on Saturday, [GM Michael Hill] was asked if Johnson would be with the team next season.
“Yes, I can say with certainty, yes,” Hill said.
I take that as probably true. Whether I like the idea or not is another story. As Maniac commenter Lane pointed out over the holiday weekend, Keith Law of ESPN think the Marlins could get a major haul from Johnson, in the form of two major-league ready youngsters and two Double-A players. The Marlins would be foolish not to listen to offers of that nature. Also, packaging Johnson with someone like Dan Uggla or Jorge Cantu can improve the package of players coming back.
To say that the Marlins will essentially not be listening to offers for a player they likely won’t control for more than another season is not really a responsible move for the team. The team should do its due diligence and listen to offers, without a guarantee that Johnson will be shipped off.
