A class signing for next season and a bonus “loan” for this. When you look at our team, style of play and where we have the most “senior in years” players, it is in our back line, on the wing. Those wingers are called on, are willing, and do, take the ball into contact with the opposing teams many times a game early in the tackle count. It not unusual in the modern game, but what is different is the way ours take it straight to the opposing forwards, time and time again, causing the opposing pack to tire early. This calls for big, fast, strong wingers, and put extra stresses on their bodies. Josh fits right into that style and we now have an even stronger, top quality back line this season, regardless of injuries and/or resting of players.
Was he essential this season, probably not, but like Jack says, this is likely a top class addition that came with an incentive to bring over early (hence the loan aspect).
Welcome Josh. Wear the shirt with pride mate.
