Conca doesn't look as good as Heppell. Doesn't mean he is not though. No one took any notice of Ellis until his numbers surprized them recently. Conca not a match winner but will do all the hard 1% all day. He will win you the ball and feed it out to your better ball users, he will attack the ball regardless of the consequences, he will frantically chase and tackle, find space in front of goal and he will remain disciplined under pressure.
It's the same problem we have had for years with our better players, he has to do what older players should be doing for him. Heppell looks great because he is feed on the outside of stoppages. Conca will overtake him in the next year or two because he will become more influential in games but Heppell will always have a better highlight reel.
