good write up nathan
i'd rank them like this:
Stephen Drew - does it all, has plus power, plus contact, plus speed(doesnt use it as often as he should)
Reid Brignac - reminds me alot of wood, i dont think he has as much power but he'll hit around .280-.290. hes not that great defensively at the position, not as fluid and his range isnt as good as Tulo's
Troy Tulowiski - good power, .270ish hitter with exceptional defense for a player his size. (Col. factor wont bring him over the others imo)
Brandon Wood i wont list here cause i very highly doubt he stays @ SS.
