I mis-spoke when I said New York. Here are NFL players by state of high school: http://www.maxpreps.com/news/J_G3Ol...ery-active-nfl-player-went-to-high-school.htm
Connecticut doubles up Massachusetts and has 71% more NFL players than the other NE states combined. It produces more than 3/4 as many NFL players as NY despite having less than 1/5 the population.
You're right about FBS players which tracks population more closely, although Connecticut has equalled Massachusetts in recent years as a source of FBS players (eg 2013, see http://footballrecruiting. /content.asp?CID=1470883). But as you go to better quality -- I said BCS -- Connecticut does better relative to Mass, New England, and NY.
BCS is an odd metric to use since that term is dying this year - but it doesn't really change much. Massachusetts actually did better than I thought they would when I looked up the past few years on r_i_v_a_l_s:
2011 NY - 32 (!!! not sure what happened here)
2012 NY - 15
2013 NY - 13
2011 Conn - 7
2012 Conn - 3
2013 Conn -9
2011 Mass - 10
2012 Mass - 12
2013 Mass - 8
