It’s not just what happened on the field. He is a great leader on and off the field and that has been a major factor
Eh? So if a player was injured for the whole season, but cajoling his team from the sideline, he could still be in the running for POTY? 
You're not 'on' the field if you're injured for the whole season surely
Yes but my point was, what he does off the field has no bearing on an award like this.
You may contact FWA and tell them.
FWA chair, Carrie Brown, said: “Leadership is intangible and often unquantifiable unless it is inarguable. Jordan Henderson is both the ultimate professional and now a bona fide Liverpool legend.
“Jordan is a player his team-mates look to on the pitch and who his rivals look up to off it. The voting criteria for the Football Writers’ Association Footballer of the Year is one who leads by precept and example and in this country’s darkest moment, Jordan, unprompted, personally rallied club captains to establish #PlayersTogether.
“Millions of pounds have been raised for the NHS and significantly #PlayersTogether is now an established collective power base for players to engage in campaigns, none more so evident in the ongoing and powerful anti-racism #BlackLivesMatter campaign. He is a truly worthy winner of our award.”
