33% made it and had a negative war or a career war of less than 3. Only 9% or 4 players in 45 years had a war over 3 and none of those were over 8.
IMO getting a quality player like Drew that has produced around 16 war over his career seems like a great trade off. The chances of drafting a player and getting any decent production is less than 10%.
I'd bet that you'd get more than that out of Drew even if he doesn't reproduce last year.
If we're basing the results on WAR, I'd bet you'd only get more out of Drew simply because playing SS virtually promises positive WAR. Drew is nearly washed up and his numbers away from Fenway and against lefties support that idea. I think the odds that Drew is a useful player for the next 2-3 years is also about 9%.
