Can't narrow it down to three so heres five.
Rivers - if fit he will stand out as expected.
Bate - I think the bloke could be the star for CAC's CV. Big, Strong, Great hands and can kick the ball accurately 60m+. If the midfield/half back line can give him some reasonable delivery, he could be anything.
Jones - Entering just his third year of footy, seems like hes been playing for years, with his hairstyle, strong build and consistant gathering of over 20 touches a game.
Mclean - as per Rivers, best player at the club at the moment.
Davey - a great footballer.
