But it wasn't until this year, when two-time NBL champion centre Gary Wilkinson was released, that the door really opened for 'The Chief', and Lemanis' faith in the young star was rewarded.
"Just to see his growth over these 100 games is very pleasing from a coach's perspective and also a club perspective," Lemanis said.
"We've invested in him as a young player and he's come through, he's improved and now he's delivering and has a bright future in-front of him."
But Lemanis still sees plenty of room for Pledger to develop, and believes solutions to some issues surrounding his game - like the struggles he displayed with his offensive footwork in Thursday night's 104-74 win over the 36ers - can be ironed out with experience.
"It's a continual process of getting better and improving and I hope that's true for everybody, I hope I'm still getting better as well.
"The more he plays, the more practice he gets through and the more comfortable he is with what his moves are going to be in those situations, the better player he is going to be. He's a pretty good one now and the improvement is going to be exciting."
Pledger was caught unaware of his impending 100th cap, but is proud of his achievements in a Breakers singlet.
"I didn't know that it was 100 to be honest, I figured I was close but it is an achievement I am proud of," said Pledger.
"I feel like the first half of the season for me was a little inconsistent but since the New Year I have been solid and with Will (Hudson) being out as well I am happy with how things are going with the extra minutes I am playing."
The Taipans are in hot-form following back-to-back wins over the Townsville Crocs and the Perth Wildcats, but Lemanis noted that a number of teams come to New Zealand in good form, but leave with a loss.
"Adelaide was on the back of a two game winning streak when they came here and were playing with some confidence too, so I actually like that we need to continue to be challenged going into the playoffs.
"We've got teams coming in who are desperate, desperate for their playoff positions and it's good for us to be playing at that intensity at this time of the year."
The Breakers are confident their club record 13-game win streak, like their big centre, will continue to grow.
