Which player has shown the most improvement this year.

[deepbluesee]

Along these lines was a segment on talking footy the other night about The Bulldogs and which players have improved on last year (they indicated only a couple from memory).
I also posted a year or two back about the whole list and who had improved on the prev year - my thoughts for that period were very few.
If we look at the 2017 v 2016 performances for each player i would be pretty confident that 75% have had as good or a better year than in 2016.

Anyone care to do an analysis:
Player    Improved in 2017 (yes/no/same/new)
xxxx      yes
yyyy      no
etc...
