To'a has strong performances in him, we saw it first hand for a very good period. what you also have to remember is that he had a stack of halves play inside of him. that's shocking for building combos. having Sezer there (hopefully) all year I think he'll be more consistent on both sides of the ball. the key for him this preseason is unlocking the ability to do it consistently.
Staines is a proven first grader, having him injury free for the entire season will help us immensely. despite him leaving, I do think Tupou is our best option on the sting outside of Staines and he'll improve on last year. left centre at the minute is up in the air but if Olam does come he's still a marked improvement on any other options we have. Naden is good depth, Feledy and Kepaoa not so much. I have no idea on Alaimalo's prospects as the last tape I have seen of him was from about 3 years ago.
Bula towards the end of the year was dragging players into position and yelling out instructions. he was also at the back when we went through that period of defending brilliantly. positionally he needs a little work, but ultimately his speed and awareness was able to make up for what he was lacking. that kid is elite. a couple more preseasons and he will be in Origin conversations, mark my words.
