That would be a great deal for the Royals.
Holland is a very very talented young pitcher that would immediately be the best pitcher on your staff. He's a power lefty that can show up with shutdown stuff on any given night.
Hell, the Rangers even extended him under a fairly team friendly deal through 2016 w/ a reasonable club option in 2017. That would be an excellent get for KC. I'm honestly a little puzzled why the Rangers would give him up.
If you can't draw a crowd, draw dicks on the wall.
