If I were the Sox, I'd make Scherzer a legit offer.
Something like 8/175 (take it or leave it.)
I know that's alot of money, but the Sox need pitching and they'll also have alot of money coming off the books for next year (Napoli, Victorino, Cespedes, Ortiz, etc.)
Scherzer will get more per year than that. He'll get more per year than Lester and possibly another year than him. Think 7/180+ If the Sox were unwilling to go more than 135 on Lester while the Dodgers and Giants were willing to pay $20 mm more, I don't see the Sox being serious bidders for Scherzer. The Tigers offered him 6/144 last offseason and were rejected.
I think the Sox blew it on Lester. Sure he got a ton of money, but that's the market rate now. 3 teams were willing to go $150mm+. The Sox are one of the richest teams, they should have forked over the money. Kelly will be in the rotation making minimal money and they'll probably have a rookie in the rotation. By 2016, they should have a few young guys in the rotation making minimum money as they have so many young pitchers ready or about ready for a shot at the majors. Just to list them for emphasis: Workman, De La Rosa, Renaudo, Webster, Barnes, Owens, Johnson, Rodriguez, Escobar. A few of these guys will be traded, a couple converted to relievers, and two or three should be in the Sox rotation over the next couple of years. That's a lot of savings as they will make league minimum. They won't need to pay a veteran 8-10 mm to fill the middle or back end of the rotation.
Plus, they have Boagarts and Betts as every days players and Cristian Vazquez catching and Swihart about to join him. They were paying Ross $3mm as a backup catcher. They were even paying Drew about $12mm. Because of these young guys coming up, they won't need to pay guys like that. They screwed up. They should have matched the Cubs offer. They'll have a payroll around $180mm, so what's an extra $3mm to ensure you have an ace.
