For serious... let's say he averages 8 wins per season over those next 4 years and you get 5 wins this season. For that you pay 130mil. At $8mil/win, that's 37 wins/296 million in value, getting you a cool 166 million in surplus value. Plus a bonus for him being elite - the 8th win above replacement is worth more than the 7th. Plus a bonus for marketability. Call it an even 200mil.
Texas can throw down Mazara (let's say 3 WAR average), Gallo (2 WAR average) and Profar (2 WAR average - I love the guy and would go higher, but being conservative). Plus Luis Ortiz or some other pitching prospects. Those 3 guys will give you 3 seasons of basically free WAR (league minimum salary) so that's 21 WAR in free value, or about 168 million in surplus. They'll earn some surplus in arbitration as well, maybe that gets you close to 200mil. The Angels will probably want you to overpay, though, so in addition to Ortiz, you're probably throwing in Dillon Tate and maybe even Martin Perez, who is healthy and pitching now, and signed through 2020 with 3 nice cheap team options. Or maybe the Angels like Brinson instead of Gallo since they need a CF. That's probably more realistic.
So there you go.... Mazara, Brinson, Profar, Tate/Ortiz, Martin Perez. If you're Texas, do you want to do that? You've got Trout, Hamels, Beltre, Fielder, Choo, Darvish... and you're praying Joey Gallo works out and that you can somehow get through the season with Derek Holland and Colby Lewis as prominent players in your rotation.
