I've just been watching a few vids of Mamo on youtube. I remember him looking pretty quick and strong when he first joined Hudds but on his montages from Newcastle Knights he looks to have been a sensational athlete when he first emerged. I know montages always show players in a good light, but in terms of raw speed and acceleration he was something else - in the speed range of a young Kevin Penny but with greater size and power.
I wonder if injuries have taken the edge off his pace which will be a shame, but if not then there is definitely a potential star in there if he stays fit and clicks with Steve Price. Definitely worth taking a punt on and will bring something totally different to what we currently have.
