I don't think he knows just how good he could be to be honest. At the moment he's tall and rangy, obviously very strong as he dents the line more often than not and has one of the better offloads going around. What he needs to work on is:
1\. Focus, which will probably come from improved fitness and experience. He tends to drift in and out of games and has come up with a couple of poor missed tackles as a result. If he improves his focus and intensity, look out.
2\. Size. He's not small but I reckon another 5kg on his frame will have him hurting blokes.
I still think he's best served coming off the bench, like Gavet as he does provide impact. Looking at the next 6-10 weeks, I reckon the forward pack could end up looking like:
8\. Woods
9\. Farah
10\. Galloway
11\. Sirro
12\. Thompson
13\. Blair
14\. Taupau
15\. Sue
16\. Gavet
17\. Akauola
18\. Seumanufagai
