For the remainder of December and into the New Year, the Engine Room will be running profiles of each player on the Essendon senior list. We will have a look at what went right in 2001 and what went wrong. What will the coaching staff want from each player and how might they be used in 2002. Today we take a look at MARK BOLTON. Bolton's ability to play almost anywhere has made him an important back up in recent seasons but that role won't sit well with him. Bolton will want to make sure he can nail a regular senior berth in 2002.

Mark Bolton played more senior football in 2001 than he had in any other season since making his debut in 1998. Despite this improved return he still would have been frustrated that he was unable to cement his place in the senior side. Every time Mark returned to the VFL side he played excellent football – a quality clubman he never dropped his head. When in the senior side he rarely let his teammates down.

Bolton has been given a variety of roles when playing senior football. He has been given run-with jobs in the middle, played in key defensive positions and occasionally found himself pushed forward. A prolonged period of time in the one position at senior level might just be what he needs to find the consistency and confidence required to cement a place in the senior side.

It goes without saying that this is an important season for Bolton. With AFL club lists shrinking it is becoming harder for clubs to remain patient and this will be Bolton’s fifth year at Essendon. That said, there is little doubt he has all the attributes required. He has a combination of height and mobility – pre-requisites for any football trying to make it at the top level. On top of this, he is as determined as anyone at the club to make the most of his chance - only time will tell.

How will he be used?

As has generally been the case for his whole career, his role will basically be dictated by which side Essendon is playing. Bolton gives the Bombers’ height in defence, endurance on the ball and a marking option up forward. If he makes the most of his early chances he could play any of these roles on a permanent basis.

What will the coaches want on match day?

The coaching staff will want to see Bolton use his endurance and height to great effect. He can excel in any of the roles given to him – they would love to see him make them pick him in the senior side. His flexibility will get him into the senior side, he must ensure it keeps him there.
