At 56kg and just 173cm tall, fullback Jake Coxsedge will rarely bust through an opposition defensive line from a kick return.

But the flighty custodian will punish lazy defence with speed and is not afraid to hit the line at speed.

"He's got a lot of speed, a lot of talent and plays with a lot of talent that's for sure," he said.

Seventeen-year-old Heydon Dover stands 10cm taller than Coxsedge and is 16kg heavier, but similarly relies on pace and a bit of stubborn strength to keep his run-on spot.

"They both deserve their spots in the team and they give it everything they've got...that's all I can ask for."

Coxsedge grew up playing for Narromine, west of Dubbo, before lining up for Group 11 club Gilganrda Panthers for his maiden first grade season in 2009.

Dover is a Blues product through and through, having played for the Bay since under 11s.

Northern currently sit, winless, on the bottom of the first grade ladder and while its consortium of youth provides a much-needed burst of enthusiasm and interest, it also represents the club's biggest challenge beyond 2010, according to Relf.

"We have a few blokes that are still only young, we need them to stick around for the next few years when it will really start to pay dividends for us."

Other Northern first grade regulars yet to have their 22nd birthday include front rowers James Howell and Stuart McDonald, hooker and halves option Isaac Upton and centres Cooper Scott and Cameron Cooper.

The Bay will attempt to rally against a wounded Kurri Kurri Bulldogs away this Saturday.
