Yep . Both those things are well within things he can control . The kicking is just repetition , aligned with coaching on how and where to hit the ball with your feet , and just really time . Fitness is all about effort . If Latu wants to live up to his potential then the gym needs to be his friend . He’s got a really good mentor in luai to make that happen.Plenty of pros and cons.
Latu is a stronger ball runner than Galvin, has better deception and short ball than Galvin and is a much better and stronger front on defender than Galvin, but doesn’t have the same level of fitness and therefore doesn’t get in positions to be on the ball and compete as much as what Galvin does, Galvin has developed a nice short kicking game, both of their long kicking games are ordinary at best, Galvin has a better long passing game and is a better lateral defender,
IF Latu makes good improvements with his fitness and kicking game, he will become the superior player.
Whereas with Galvin , he can only get so fast , he can only develop so much .
I think his development will really be in strength intangibles . As he gets older his strength will grow , and his ability to brush tackles and stand in tackles will get stronger . But that will be at the expense of his speed off the mark . And he’s already fairly slow .
