Player who can play 2-3 positions

[adifairus]

you just need to check the highlight ability of multiple position player and compare with the grey ability with specific single position player,

for example:
single DC got grey crossing ability
single DL/DR got higlight crossing ability
multiple DC/DL/DR got highlight crossing ability

but don't just check on crossing ability only, please check others ability as well that make DC and DL/DR different

the ability that make centerback and fullback different is Heading, Strength, Speed & Crossing

your multiple position player is more suit to DC if got higher Heading & Strength than speed & crossing

and suit to fullback if got higher speed & crossing than strength and heading.
