I think it is a good idea getting Gilbee, but getting rid of Hodge is an iffy.
Hodge is an animal...playing while injured and 1st tagged yet scores okay (not great, but still okay).
I guess it's the same reasoning though as the people who traded Ablett out - his price is going to drop enough that you can get him back on your team for cheap if he looks better in 3 or 4 weeks.
