SELECTOR Mick Deegan believes that Dublin need to be wary of over training if they are to avoid a repeat of last year's campaign when they were over-run by Mayo in the All-Ireland semifinal.'In our eyes it was something we did a bit too much of last year, but at the same time it's part and parcel of the modern game that you have meet up to a certain requirement.' There has been anecdotal evidence of members of last year's underage set up getting up as early as 5am to train, but Deegan at the same time believes that this current Dublin panel is well able to meet any physical challenges. 'If you look at the team that won in 2011, the average age was 27 and only two were over thirty. 'You see the fruits of the work that has been done in the past few years. We have won two under-21 titles since 2010 and reached back to back minor finals. The 2011 Sam Maguire holders begin their O'Byrne Cup Campaign away to Carlow this Sunday before hosting DCU in an intriguing clash the following Wednesday in Parnell Park. The Metropolitans complete their round robin campaign at home to Wicklow four days later and Deegan believes these three games along with this week's Dub Stars challenge gives the management team an opportunity to look at players they wouldn't normally see. 'We wanted to have a lot more trial games but unfortunately it didn't work out that way.' The former Ravens man has reiterated the managements intention to search high and low for talent as Dublin aim to regain to their 2011 All Ireland crown. 'We have contacts in every club so we won't be overlooking anyone.' Along with the Ballymun players who are tied up with All Ireland club commitments, the two Brogans, Alan and Bernard, are currently unavailable along with Eoghan O'Gara, Mick Fitzsimons, Paul Flynn and Bryan Cullen (the latter currently away on honeymoon). As such the game offers some of the peripheral members of the squad to stake a place on the team. St Sylvesters forward Micheal McCarthy is likely to feature again and his club manager, Gabriel Bannigan believes that the stylish forward will be eager to prove a point after being overlooked to a certain extent by Pat Gilroy last season. 'I thought Micheal did well last year, but he picked up an injury against Kildare and that was a pity because he was going well before that. 'Surprisingly he didn't get a look-in during the league and I thought he would have. Apart from those O'Byrne Cup games which he did well in Michael hasn't been given a chance.' McCarthy was involved in this week's Dub Stars challenge in Blakestown alongside Kian Cleere and Ross Hazely and Bannigan believes this is a good opportunity for the trio. 'As a Dublin manager you would want to take a look at as many players as possible to get a team together for the league and then you use your league to get things right for the championship. 'I think it's a very good opportunity for the Syls lads to impress the new manager.'
