Adelaide Crows ruckman Sam Jacobs a marked man, says Dean Brogan DEAN Brogan says Crows ruckman Sam Jacobs is suffering the effects of being a marked man in 2013. After a week spent studying tape of Jacobs in the lead-up to today's clash between Greater Western Sydney and Adelaide at Skoda Stadium, Brogan said teams were reacting to the big redhead's dominance in the midfield. "Last year he probably got under the guard of a lot of teams and this year coaches and players are putting more time and effort into him," Brogan said. You really sit down and break his tape down and try to look for strengths and weaknesses. I think that's what it is. He's going to have to raise his game to another level and hopefully it's not this week. Brogan and Giants teammate Jon Giles will tag-team Jacobs today and are determined to keep the Crows tapman searching for his best form - not finding it. "Last year I thought he should have been All-Australian," Brogan said. GWS Giants ruckman Dean Brogan says Crows ruckman Sam Jacobs is now being targeted. He's not going as good as what he was last year but he's an elite ruckman and myself and Gilesy have our work cut out for us today. I'm sure he's looking to come out and destroy us. I really rate Jacobs, he's a top player and we can't let him get back into his All-Australian form. Asked about the technical differences in Jacobs' game in 2013, Brogan said he had noticed changes - good and bad. "I don't want to say too much against him but he looks like he's not jumping as much as he was last year," he said. But he's doing some different stuff - hitting the ball over his head - so he's doing some good stuff there. Crows ruckman Sam Jacobs is finding it tougher to dominate this season. Today's game is Brogan's first since a three-week stint on the sidelines for a high bump on St Kilda's Jack Newnes. The suspension all but killed off Brogan's hopes of reaching the 200-game mark before his career comes to a close at season's end. To notch up the double ton Brogan will need to play 13 of the final 15 games of the season - a number that was never in the Giants' planning. "I'm going to have to play a lot more footy," the Port Adelaide premiership player said. It would be a nice thing to get but really I retired two years ago. These are just bonus games. If I get there that'd be great but if I don't I'm not going to lose sleep over it. Brogan needs to play just one more game after today's match to qualify for the AFL's 200 Club, which acknowledges preseason games. That will land him a couple of free tickets to home and away games - and one to finals - for the rest of his life. After finally hanging up the boots Brogan hopes to become a full-time member of the Giants' coaching staff next season. He is enjoying life in Sydney and wants to ensure his stay with the Giants encompasses their rise up the ladder - not just the early days in the doldrums. "Originally I was meant to come up here and play for one year and coach for a year," Brogan said. But I've spoken to (GWS football manager) Graeme Allan and there might be an opportunity to stay on and coach after this year. That's the plan at this stage.
