The answer to your question....
I have no idea about Ashley Ward (and being a pedant it is not the answer to the question posed anyway), however the second one is correct in that Nathan Blake was the other one who has been relegated 5 times,
1993–94 at Sheffield United,
twice for Bolton Wanderers in 1995–96 and 1997–98,
in the following season for Blackburn Rovers
and in the 2003–04 season while at Wolverhampton Wanderers.
Cannot confirm whether he ever scored 20 goals in a season though.
