Olam is just raw power really, with decent pace.
In other era's where there were O'Conner, Lyons, ,Renouf, Inglis ect he would have just been rated a tough - hard centre.....in fact he just runs "through" players and close to the line especially, has made half comitted defence including Manly's - look ordinary.
Olam is a Solid player who hits hard and usually defensively great like most at Storm, but have seen him have sloppy mits and not always great at getting his winger away....more a solo crashball runner, which is his most effective Trump card.
In the current game, there is only 1 who stands out to me like the dangerous centres who turned games on their own and that would be Staggs in the 3 games a season he plays, or Latrell Mitchell when picked at centre.
I think in general, centres these days the role is different.
Lets go back to 80's and 90's it was all about the sweeping ball movement to get to your strike centre who would use a step, fend, or pure speed to make the break.
Since 2000's the game has shifted far more prominantly to blowing up the ruck/middle and the backline shift works off this momentum to use that 2nd man play (usually involving a fullback) , to put away the winger.....the centre will sometimes be often used as a decoy/option runner, with the key goal to hit the unmarked winger....though the short play to the centre is still often used close to the line with defnce backpeddling or in 2 minds to crash over the try line...
This does not mean it's not a bonus to have a super flashy centre, as Koula showed the other night, gaves another dimension, as early ball he can basically run a line outside his centre and create the defensive winger inwards to provide his winger open spaces.
I just feel the games evolution has seen the "Star centre" almost extinct with the key roles of dummy half and fullback becoming far more important for the reasons above...
To see a Flying Koula in action does still add so much strike and I know 1 thing for sure, opposition will have him in their checklist as a man to watch in the future which will only help Tom and others create mayhem.
