Whether he has a two-year offer or not, it appears he'll be able to get at least $4million for his services next season from someone.  At best (or worst) Tigers would have to offer a vesting 2nd year option probably tied to appearances rather than a metric that actually helps the club, like, I don't know K's.  Consider: you or I could appear in 50 games season for Tigers - I mean, Dolsi appeared in 42 last year.

Anyway, I digress - Lyon isn't too expensive or inflexible, he's not good.  Season averages - 4.4 ERA, 1.4 WHIP, only a 2 -1 K-BB rate with a 4.5 K per 9 IP rate.  And, most of this was in NL?

This scattershod strategy of throwing a bunch of lower paid arms at the spring training wall and see what sticks/comes north is not going to work.
