New Storm five-eighth Blake Green says he's a much-improved player after his time in the Super League.

Rugby league is open to second chances. 

By his own admission Blake Green was not mature enough for the NRL early on, content to just be there and play first grade.

Now he returns to Australian shores ready to prove he is much more than your run-of-the-mill footballer.

The Storm announced back in June last year that it had signed the former Eel, Shark and Bulldog on a two-year deal.

Green has spent the last three seasons in the English Super League, originally for Hull KR before moving to powerhouse Wigan.

He now returns to the NRL at the age of 28, ready to address some unfinished business he left during his first stint in the competition.

"It wasn't as successful as I would have liked, I was only a young kid. I left here when I was 23. I was just happy to be playing first grade at the time," Green told NRL.com.

"Going over there has increased my understanding of the game and gave me the desire to come back and be a successful half in the NRL, which I am going to aim to do over the next couple of seasons."

When asked to compare the Blake Green that left the NRL in 2011 to the one we will see this season, the man himself is adamant the two players are now miles apart. 

"Totally different, I've matured and grown up," he said.

"Just the amount of experience I gained over there, I was lucky to be at a successful club and play in some big games and learn how to deal with being under pressure and expectations."

Green proved just that in Wigan's 2013 grand final triumph, where he was awarded the Harry Sunderland trophy for a man-of-the-match performance.

When Green arrived amidst new surroundings in Melbourne there was one familiar face he recognised at AAMI Park.

Storm assistant Justin Morgan coached Green during his first season at Hull KR and has a better insight than most into the change the five-eighth has undergone.

"He is a more confident footballer now, a more complete footballer," Morgan told NRL.com.

"The biggest learning curve for him was that he was the number one man, so to speak. Over there he was signed as an imported player and when that happens there is an extra responsibility, like a lot of players that go over there to reboot their careers.

"Sometimes when you haven't established yourself your confidence can take a little bit of a hit but he went over there and that confidence built and he's come back a very good footballer.

"He is a genuine footballer. He likes the game, thinks a lot about the game and I saw him really develop and mature as his confidence grew."

"I certainly had no hesitation to say that he would fit the Melbourne Storm model exceptionally well and I think he has already proven that with his training."

Since the departure of Gareth Widdop to the Dragons in 2013 the five-eighth position in Melbourne has resembled more of a revolving door than anything else.

Ben Roberts (Castleford Tigers), Joel Romelo (East Tigers) and Cody Walker (South Sydney) all wore the No.6 at some point last season but have since moved on.

Even Cameron Smith had a go, while Ben Hampton was given more of a taste at first-grade level and after a strong preseason appears to be Green's biggest competition for that staring spot.

While the 23-year-old Hampton may be the incumbent it is Green, who already holds more than 40 games of NRL experience, who may get first crack.

"One of the other good things that Blake brings is that he is a good organiser and a good talker. That might relieve some of the stress and some of the pressure that is on Cooper," Morgan said. 

"It is a good situation to be in and we are hopeful that competition for places continues."

For the well-travelled Green, the Storm will represent the sixth team in nine years he has been a part of. 

Having now made the move to Victoria with his wife and young son the experienced campaigner has had enough of moving boxes and is now focused on becoming a key cog in the Melbourne machine for some time to come.

"That's the plan, I moved around a little bit when I was younger and found my feet overseas as I got a little bit older and got a bit more confidence," Green said. 

"Hopefully I can nail down a position here at the club and stay here as long as I can."

Melbourne kick off their season next Monday night at Jubilee Oval against the Dragons.
