Essendon host Port Adelaide at Etihad Stadium on Saturday night in a big game for both clubs.

The Power were impressive in a narrow loss to Adelaide last week while the young Bombers led the Kangaroos for a half.

These are the burning questions.

-       Has Essendon pulled the right ruck rein? 

James Hird suggested Todd Goldstein was the difference in Essendon’s loss to the Kangaroos last week.

Shaun McKernan said the match was a steep learning curve.  The former Crow enters Saturday’s game against the Power as the club’s only recognised ruckman.

Hird said he resisted playing Jonathan Giles because he wants to see more consistency from the former Giant in the VFL.  He was also concerned the effect playing an extra big man may have on the side’s ability to run and spread.

Port Adelaide's new ruck combination has taken a while to find its feet, but Matthew Lobbe and Paddy Ryder were more than handy last week against the Crows, booting five goals between them.

McKernan spoke glowingly of his relationship with Hird during the week and he will be keen to repay the Coach’s faith. 

-       Can the Bombers keep the Power scoring in check?

Port Adelaide may not have won a lot of games recently but it is still managing to kick some decent scores.

It’s scored more than 100 in four of the last eight games with Chad Wingard and Jay Schultz among the competition’s top goal kickers.

North Melbourne's run and attack is similar to the Port Adelaide’s so the Dons will be well versed in how to slow the Power’s surge forward.

Michael Hurley will again lead the Essendon defence, but the midfield will be vital in slowing the Power’s ball movement. 

-       Is Cale Hooker a permanent forward?

The All-Australian defender took 13 marks last week against the Kangaroos and had five shots at goal.  While his conversion was a little off, his ability to provide a target and a strong contest drew praise from coaching staff.

‘Swingmen’ are becoming more prominent in the game with Jarryd Roughead highlighted by James Hird as one such player who uses his versatility to great effect.

The Bombers have three players who can play well at both ends with Hooker, Michael Hurley and Jake Carlisle all capable forwards and defenders.

The flexibility they provide is extremely valuable in the modern game.
