Have to evaluate a deal with Dickey, not Niese. Look at nearly all southpaw development. Pull up the top 10 lefties of all time. Nearly all come into their own at 26/27 years old. Just the way it is, and especially so with a non-power pitcher. Not saying Niese is HOF worthy and not saying that his development will 100% take a step forward next year, but the precedent for young lefties is congruent with his success last year and the trajectory is typically for further improvement.
If he works out and hopefully Harvey and Wheeler can also be mid to top if the rotation talent, that is a cheap, quality core that can last for 5 years. Have to keep that intact as I see it.
Need to see what a Dickey plus prospects can get us and take the highest impact player we can garner. Maybe it is Myers, but maybe not. Would think that Dickey with a 2 year extension to average out to 3 years at $8 or $9 per plus say Flores and Familia is very close for KC. Helps them win now with Dickey, gives them a bullpen option with upside in Familia for now and the future and an out year prospect with upside in Flores.
