Paul Gallen has an injured foot. NISSAN SuperCoaches face a front row crisis this weekend. Origin, byes, injuries and off-field indiscretions have taken their toll, with Cameron Smith (eye), Paul Gallen (foot), Trent Merrin (suspension), George Burgess (disciplinary suspension), James Graham and Aiden Tolman (both on the bye) unavailable. All but one of these players are in the top eight most popular front rowers in SuperCoach this year. And if Robbie Farah and Aaron Woods fail to back up, some SuperCoaches may be unable to field a front row at all. That said, don't tear your side apart just to get a full complement this week, particularly at this stage of the year when many SuperCaoches have four, five or even six guns in the front row. Make sure to check for dual position flexibility with back rowers, and if you have to rely on an automatic emergency, so be it. All these players are in the elite class of SuperCoach keepers this year (apart from Tolman, but he has the added advantage of playing the tough bye in round 18). So don't sell just for an extra number this week, especially if an emergency is available. A golden rule of SuperCoach is to never sell a keeper. THERE has been a dearth of genuine cheapies over the last few weeks - and this round is no different. The only decent option is Storm youngster Mitchell Garbutt, but even he is not assured of a spot with Origin players back (although the injury to Smith could create some forward game time). But the cheapie drought could be over as early as next week. Melbourne fullback/half Ben Hampton, South Sydney prop Tom Burgess, Canberra winger Sami Sauiluma and Penrith back James Roberts are all set to play their second games this weekend. If they post decent scores, they will be prime buys for next week. A HOST of popular cheapies are set to peak over the coming weeks, making them essential cash-ins. In particular, Anthony Don, David Nofoaluma and Suaso Sue are must-sells over the coming weeks because they are not keepers and won't play round 18. Join Tom Sangster and Cameron Tomarchio for week sixteen Buy, Hold or Sell. Corey Parker He's expensive, but Parker is playing too well not to have, even if you have to wait until after his looming byes. Jamie Lyon Lyon is the best centre/wing in the history of SuperCoach, has no byes remaining, won't play Origin and is a keeper right through until the end. Shaun Fensom The Canberra tackling machine won't play the next tough bye week (round 18) but is a hold nonetheless given his awesome SuperCoach form. If you didn't sell him last week, now could be the time. His suspension and bye schedule have reduced availability. And Paul Gallen and Corey Parker are calling. A quiet week for SuperCoaches with no obvious cheapies and Origin players backing up, which usually means they score below their potential. If you can field a solid 17, save your trades for later when they will be more useful." - Matt Mullen (2009 winner) Depending on who the home side is this week and how vocal the supporters are, Shayne Hayne could be a good smokey for a big score. If you aren't concerned with round 18, Woods and Fensom look the goods and ensure you check the late mail on Gallen." - Martin Bigg (2011 winner)
