Even after being suspended for Port Adelaide's agonising Elimination Final loss to West Coast in 2017, Tom Jonas will not change the way he goes about his football in 2018.

Jonas was handed a two game suspension for rough conduct in round 22 against Luke Dahlhaus, missing the extra-time loss to the Eagles in the first week of the finals.

"I'm probably not as talented as some and I need to do that [play on the edge] to perform at a high level, so i've got to do that." Jonas told afl.com.au

Its been a costly few years for the defender, after copping a six-week ban in 2016 for a dangerous strike on Andrew Gaff.

Jonas will be a part of the Power's leadership group in 2018, after finishing third in the best and fairest and being included in the 40-man All Australian squad after a career-best year.

"Internally, we felt it wasn't as much an aggression thing, as much a technique thing, so I've been trying to do that."

"I've probably worked a little bit with Bass [defensive coach Nathan Bassett] around the technique side of defending a little bit, more so from last year's incident than the year before, just around being able to stop my opponent without the risk of slipping high."

With just two warm-up games remaining for all 18 clubs, Jonas expects the Power to take a strong 26-man squad to face the Eagles on Sunday.

In 2018, we have seen the inclusion of AFLX, while reducing the number of JLT Community Games from three to two, a format Jonas feels more comfortable with.

"I think two is the right number because you can always play an internal [trial] if you need. Three just becomes a little burdensome on some of the boys."
