In chibear55's defense I do think the top 3 guys, likely Price, Zimmermann and Cueto will get something close to Scherzer money. Your point is well taken in the depth though and there might be some reasonable contracts to be had.
Zimmermann and Cueto will get closer to Lester money. Price will get closer to Scherzer money IMO.
That said. Lets not forget about the other pitchers out there via free agency, and the possibility always looms big to me with smaller market teams such as Cinci, Colorado, Oakland, Miami, KC, Minnesota for example, that may have pitching and know they won't be able to extend or want to put more prospects in their system that don't necessarily have to be the great ones.
This is where I might look first.
Also, the Cubs had stated that they are looking for TOR pitching which could mean a solid #2 to pair with Arrieta, although an equal to or better than Lester would naturally be the best of both worlds.
