I'm ok with going after Kesler but not if it means trading our 3C because that pretty much ensures that Kesler will be taking that spot. I'll take an adequate, if underwhelming, 3C(Sutter) and an improved top 6 over a slightly improved 3rd line and garbage on Crosby's wing. The 3 center model only works if the entire 3rd line is solid and that wouldn't be the case by simply getting Kesler. And, given the price, getting Kesler looks like it would be the only real impact move we'd be able to make.
Obviously the ideal situation is to have quality depth through all 4 lines but that's not happening this year. Not even close. So, given the choice, I'd rather load up our guns(Sid/Geno) and hope for the best.
