Jack Viney tries to evade James Frawley at Melbourne training. WHEN it comes to trading in SuperCoach, the secret is in the timing. The theory behind building a winning SuperCoach team is simple - buy cheap players at the start of the year who score well early, then trade them out and use the cash you gain to fill your team with A-grade stars. In practice, it's a little more complicated, especially when injuries, form and the unpredictable nature of our great game (exhibit A: Justin Westhoff) throw our best-laid plans into chaos. But, barring a corrective trade or two, most SuperCoach players will have a bunch of healthy cash cows that are fattening up nicely. Our Port Adelaide defenders have all put on healthy price gains, as have midfield guns like Ollie Wines and Jaeger O'Meara. When do we start thinking about cashing them in? Ideally, the stars will align so you can trade out two rookies at the top of their price, snap up another cheap youngster who is about to shoot up in value and grab a proven star who is available at a bargain price. The perfect alignment hasn't happened yet, but the elements are starting to get closer together. The secret to success is taking the plunge at the right moment - you never know exactly when a rookie is going to produce a huge score or a star is going to cop an early injury and drop in price. Below is a list of popular rookies with our assessment on when the time is right to offload them. We also need to search for the other ingredients in the perfect trade. There are some cheap players worth looking at this week - Sam Mayes, Michael Evans and Taylor Duryea have all played two matches and are about to go up - or next (keep a close eye on one-gamers Sam Docherty, Majak Daw, Jackson Macrae, Max Gawn and Tom Lee). If you make the move and trade, who do you use the cash on? Look for guns you know you can rely on later in the season who are available (relatively) cheap. Taylor Walker has dropped $74,500 this season, teammate Patrick Dangerfield is down $69,300 and even superstars Dane Swan, Josh Kennedy and Jobe Watson are down on their starting price due to one poor score. And if you haven't got Gary Ablett, he's available for $59,300 less than he was two weeks ago. The list below of rookies who may be ripe for trading includes each player's average, their price gain this year and their breakeven this week - the score they need to maintain their price. Once the average and breakeven even out, the player's price plateaus and it's trade time! This week we are only looking at rookies who have played all four matches. JACK VINEY (Melbourne) Position: Midfielder Average: 61.5 Price: $193,400 Price change: +$83,900 Breakeven: 28 Next three: Brisbane, Carlton, Gold Coast Verdict: Last week's score of nine hurt plenty of our scores, and will also put a big dent in Viney's money-making potential. The first rookie in the trade queue - if you're bold, this could be the week. BRETT GOODES (Western Bulldogs) Position: Defender/midfielder Average: 101 Price: $294,000 Price change: +$165,800 Breakeven: -28 Next three: Geelong, West Coast, North Melbourne Verdict: Will be making money for a while yet, and who is scoring better than him anyway? Lock him in for your starting line-up. JASPER PITTARD (Port Adelaide) Position: Defender Average: 76 Price: $235,700 Price change: +$107,700 Breakeven: 12 Next three: West Coast, North Melbourne, Richmond Verdict: Port has had a dream run so far, playing Melbourne, GWS and Gold Coast in the first four rounds. It gets a bit tougher from here. Hold for now, but take a close look in a couple of weeks. JAEGER O'MEARA (Gold Coast) Position: Midfielder Average: 83 Price: $252,900 Price change: +$137,000 Breakeven: 2 Next three: GWS, Fremantle, Melbourne Verdict: Has had a couple of quiet matches but has a safe place in the Suns midfield. Plenty more cash to be made yet.

And unlike O'Meara, he hasn't been playing against men for a year to prepare. Should be a safe bet until the mid-year bye rounds, and if he keeps up his average you'll nearly be able to do a straight swap for a premium midfielder. LEWIS STEVENSON (Port Adelaide) Position: Defender Average: 69 Price: $222,700 Price change: +$106,800 Breakeven: 9 Next three: West Coast, North Melbourne, Richmond Verdict: See Pittard, but with a slightly lower average so he could go to the trade table first. The positive about all our cheap Port defenders is they are mature bodies so they shouldn't need a rest at any stage. CAMPBELL HEATH (Port Adelaide) Position: Defender Average: 73 Price: $236,200 Price change: +$120,300 Breakeven: -5 Next three: West Coast, North Melbourne, Richmond Verdict: See above. If you've got all three Port defenders, next week could be the time to cash in one - especially if Brisbane's Sam Docherty produces another good score this weekend. NICK KOMMER (Essendon) Position: Midfielder Average: 61 Price: $161,500 Price change: +$52,000 Breakeven: -22 Next three: Collingwood, GWS, Geelong Verdict: Hasn't made a lot of cash yet but may not be in the Bombers' best 22. Watch the Anzac Day teams and if he doesn't make the cut, it's time to jump ship. Essendon's Nick Kommer takes a strong mark. SAM DWYER (Collingwood) Position: Midfielder/forward Average: 73 Price: $233,000 Price change: +$136,800 Breakeven: -2 Next three: Essendon, St Kilda, Fremantle Verdict: Survived the return of Dale Thomas and Alex Fasolo which is great news. Another mature-age recruit who seems a safe money-making bet for a few more rounds at least. LUKE BROWN (Adelaide) Position: Midfielder/forward Average: 55 Price: $200,600 Price change: +$65,100 Breakeven: 34 Next three: Carlton, Hawthorn, GWS Verdict: Rising breakeven is a worry, and a score of 12 in Round 3 will be in his rolling average for two more weeks (player prices are calculated using a rolling average of the past three matches). Prime trade bait for Docherty next week. MARK BLICAVS (GEELONG) Position: Ruck/midfielder Average: 54 Price: $188,800 Price change: +$72,900 Breakeven: 2 Next three: Western Bulldogs, Richmond, Essendon Verdict: Just keeps producing those 50-odd scores. If he keeps going on that path he'll reach his top price of about $270,000 in Round 10. He's not that far from it now a couple of rucks will be on the bubble next week. Needs a big game to stay safe!
