Bringing Kerevi back to a super club lifts that clubs profile domestically and globally, attracting more support and sponsorship, it makes the club more competitive and lifts the teams rugby IQ and helps retain and attract players to your club.
If I could chose an international player for each of the Australian Super Rugby teams, I would have Ardie Savea at seven for the Force, Aaron Smith as the Rebels half, Eben Etzebeth in the Waratahs, Samu Kerevi as the Brumbies twelve and Malcolm Marx as the Reds hooker. The injection of these players would make the Australian Super sides so much more competitive, watchable and marketable.
