1. Nothing but Gray skies for the Pies
The Magpies had no answers for Robbie Gray as he steamed towards half-time with four goals and seven score involvements. He was the difference as the Power built - and held onto - their 17-point lead despite the Pies winning the second term by four points. He also took an incredible second-quarter mark when the ball was popped over his head; he ran back with the flight and got his hands to it despite the close checking of Tyson Goldsack. His highlights reel continued into the third when he fired off a handpass to Matt White while being tackled by Lynden Dunn that resulted in a goal, before he celebrated his fifth 10 minutes later. The Pies got numbers back in the last quarter and he didn't add to his tally, but he ended the game as best on ground with 5.1, seven scoring involvements and five marks.

2. Is this the real Port Adelaide of 2017?
It was a great win for the Power, with their 31-point victory effectively ending Collingwood's chances of playing finals and throwing the spotlight back on Nathan Buckley. It was the first time they've won two in a row since rounds five and six with inconsistency plaguing much of their season. On Saturday, they backed up their 40-point win over the Brisbane Lions with a compelling display that featured awesome forward pressure, breakaway speed from the centre clearances that all too often resulted in a score, and their 10th third-quarter win for the season that starved off any hope of a Magpies comeback. The challenge now for Ken Hinkley's men is to do it again when they host Richmond next Saturday night if they're to convince the competition of their top-four credentials.

3. White's alright
It's all about making the most of your opportunities, and pacy Power midfielder Matt White did just that. The 30-year-old got a late call-up when defender Matthew Broadbent went down at training with an ankle injury on Friday, but in reality, was the perfect replacement for Jared Polec, who hurt his hamstring last week. White, who has played one AFL game this year, was involved in the Power's first score when he burnt off Tyson Goldsack with his trademark speed to set up Robbie Gray three minutes in. He kicked a point himself before hitting Gray inside 50 a second time midway through the first, which gave the Power a goal and a 21-point lead. He executed a bruising tackle on James Aish in the second that won a free kick, and kicked a goal in the third that was a return gift from Gray. With the Power expecting Polec to be available next week, it will be interesting to see what they do with the former Tiger at selection as he didn't do a great deal wrong in his first game since round four.

4. Reid's right but Brodie owes him
Collingwood swingman Ben Reid started his first game since round eight on the bench, which kept everyone guessing as to where he'd line up. He played in attack in his last game, but on Saturday ran into defence and manned up Jackson Trengove. He started well and was the Pies' equal leading possession winner at quarter-time with Jack Crisp (nine apiece), having worked his way up and down the ground. He went in and out of the game, which is reflective of someone who hasn't played since May, and ended with 20 disposals, eight marks and a goal. He'll also leave the MCG with a sore head and hopefully an apology from teammate Brodie Grundy after the ruckman attempted mark of the year on the collective heads of Reid and Charlie Dixon in the third term. The premiership Pie finished the game, but it wasn't ideal given his horrible history with missing games through injury. 

5. The welcome return of Fasolo's flair and form
With their season seemingly shot, there were few positives for the Magpies. But, they would have been buoyed by the enthusiasm and form showed by forward Alex Fasolo. The 25-year-old, who took time out in round 11 because of an ongoing battle with depression, kicked two goals from 11 possessions and took six marks. He was the most dangerous forward for Collingwood with Darcy Moore largely unsighted until the final term, but the best bit was the energy he played with. He marked on the lead three times, ventured up the ground in the third quarter to win the ball on the back flank, and was involved in Moore's goal that opened the final term. It was an encouraging display from the Magpie as he broke away from opponent Tom Clurey time and time again and gave his team some hope ahead of the ball.
