Yes that should absolutely be more than enough. Don't rate him as a winger so hopefully he delivers at fullback or potentially centre moving forward.
If he kills it at FB with tackle breaks, line breaks, assists, and tries, plus try preventions and low try causes over the next 3 years, then he will get himself the big contract he wants either with us or somewhere else.
He does come across as a genuine footy player, not just an athlete. He has the passing game and spontaneity to play at centre from what I've seen, though I don't recall much about his defense.
TBH getting a bit sick of this new trend of players/agents going on about being able to play FB and therefore wanting Tedesco money. Did Raelene start that by talking about rockstars or something?
