I think Caro is a fantastic prospect - strong and quick, makes big metres, breaks/busts etc. He's similar to Leroy Cudjoe in many ways but ahead of Cudjoe at this stage of their relative developments.
He has his weaknesses but these are due to inexperience IMO and a lack of confidence.
Sadly, he seems to be behind Robertson, Dixon, Colbon, O'Callaghan and probably Melling both this year and next. Again, this makes the original signing of Colbon an odd one and the re-signing of Robertson a barmy one. Given our lopsided resources, I'd have given Caro a lot of game time at right centre in the U20s this year in order to see if he can hold that position down and maybe press for the first grade there. I've said this before but we have almost every 2012 player re-signed for next year so we have almost no leeway to change the squad (im)balance with new players. I hope the infamous review takes note of this.
As things stand - limited opportunities, no sign of a new coach for 2013 etc. - Caro is at a bit of a crossroads not of his own making. Can't blame him for looking at options, if that is what he is doing.
