I don't know if this was the reason in the finals but I was told in 2016 by someone employed by the club that the coaches and other defenders love the way Blicavs can play in the midfield and run back hard to help our defence. Blicavs in the middle effectively equals an extra defender.
Worked a treat Friday night, all that great work he did in defence very nearly got us over the line.
Blicavs in the middle effectively equals one less midfielder is another way of looking at it as well.
