SuperCoach Studs and Duds: who starred and who stunk it up in Round 21 Leader ... Travis Boak was immense in Port Adelaide's win. Who starred and who stunk it up in Round 21. Hawks Stud: Captain Luke Hodge (130) returned from injury and showed no signs of a broken finger. Grant Birchall (106) also returned from a long injury aly-off and was instantly crucial to the Hawks with his run off half-back. Hawks Dud: Jarryd Roughead (60) continued his lean run of late and only kicked a goal in the final moments of the match. Brian Lake (49) had his hands full minding Travis Cloke and wasn't able to provide his usual marking prowess. Magpies Stud: Dane Swan (129) and Scott Pendlebury (110) continue to lead the Magpies midfield division. Rookie ruckman Brodie Grundy (93) showed he is a player of the future with a stellar performance as the Pies lone big man. Magpies Dud: There was no bigger dud than Heath Shaw (37) on Friday night. The usually attacking half-back spent time marking Lance Franklin at times and looked like he didn't want to be out there. Loss ... Brett Deledio was excellent despite Richmond's defeat. Tigers Stud: Brett Deledio (143) was everywhere for the Tigers but was somewhat of a lone hand. Ivan Maric (118) won the ruck battle against Robbie Warnock while Daniel Jackson (100) continued his excellent season. Tigers Dud: Dustin Martin (25) had an absolute shocker at the MCG as perhaps his contract situation starts to take its toll. Tigers captain Trent Cotchin (62) had to deal with some close checking and was a bit sore after an early big hit. Blues Stud: Midfield trio Kade Simpson (126), Mitch Robinson (121) and Brock McLean (119) stepped up in the absence of Chris Judd to spearhead the Blues victory. Andrew Walker (110) also returned a much-needed hundred for his owners. Blues Dud: Chris Yarran (45) continues to frustrate fans and had little impact on Saturday. Josh Bootsma (5) was taken to the cleaners by Jack Riewoldt before eventually being subbed out. Power Stud: Captain Travis Boak (172) was immense as Port saw off the Suns (35 touches, three goals) while fellow midfielder Matthew Broadbent (116) was also important. Straight-kicking forward Jay Schulz (114) also booted three majors. Power Dud: Jasper Pittard (35) didn't have the best of days in defence and wasn't able to provide he usual run and carry. Cameron Hitchcock (11) didn't last long and was subbed out in favour of the midfield impact of Ollie Wines. Suns Stud: Harley Benell (137) was sensational for Gold Coast, collecting 28 touches and three goals. Danney Stanley (118) showed he still has plenty to offer at AFL level while young ruckman Daniel Gorringe (98) outpointed captain Gary Ablett (97). Suns Dud: Seb Tape (18) was knocked out by a brutal hip-and-shoulder and took no further part in the game but his replacement Jackson Allen (19) had little impact after shedding the red vest. Bombers Stud: Jobe Watson's 116 again showed his resilience. Brendon Goddard (110) was a rare defender to fire this weekend, while early goals boosted Jake Melksham to 120. Bombers Dud: Dyson Heppell was subbed out at the first break, limiting him to 39. He has a foot injury. Just 53 for Kommer, who has slipped the past month. Kanagroos Studs: A monster 162 for Drew Petrie. Todd Goldstein joined the party late with 124, while Levi Greenwood (120) had 23 first-half disposals. Kangaroos Duds: Not many. Brent Harvey (72) missed the party - something he hasn't done much this year. Eagles Stud: Scott Selwood tried hard from start to finish, registering 119, but had few mates. Wellingham (101) was the only other Eagle to hit three figures. Eagles Dud: A fair effort by Josh Hill - he played the whole game for eight points. Lucky his sole kick was a goal! Josh Kennedy scored just 55 and failed to boot a major. Cats Stud: Joel Selwood yet again. The skipper booted four goals for 144 points, while Jimmy Bartel was back to his best with 135. And how about Mark Blicavs? What a return - 115 against Dean Cox if you don't mind. Cats Dud: Not many missed the party. Corey Enright (88) let a few down, while Harry Taylor (46) and his fellow defenders weren't required too often. Lions Stud: Joel Patfull (127) put in a big second half to break the ton while young gun Sam Mayes (125) kicked four first half goals. Veteran superstar SImon Black (114) was at the heart of everything good. Lions Dud: Rohan Bewick (22) had no impact despite playing the whole game while Andrew Raines (40) had the job on Tom Scully. Giants Stud: Stephen Coniglio (120) was superb on a tough night for the Giants. Toby Greene (91) had 31 touches but his disposal efficiency kept him from posting a bigger score. Giants Dud: Co-captain Callan Ward (53) struggled to get into the game at any stage while Jonathan Giles (35) was unusually quiet against the Lions but kicked one goal.
