Is he worth £500000 for Quins? Would you rather Dom, Earle and Marchant or Sinckler and Marchant..... Who is likely to win us more games? You can’t have them all and Sinckler is never likely to play more than half the games at best! Sinckler’s salary is probably = to Dom + Earle + a squad player next year!
Great player and everyone would want him but you will always need good cover for him, so can you spend so much on a player not around all the time.
