But Lamont points to the strides made by Morgan and Scott Williams this season following the departures of Australian No.8 David Lyons and Regan King last year.
And the Scottish international claims the next generation of Scarlets stars are ready, willing and able to take up the mantle and provide a smooth transition into next season.
"When there has been transition there has been enough depth here and even when boys are away at internationals we still compete really well," Lamont told the South Wales Evening Post.
"When people move on it is natural, but there have been players behind them knocking on the door. It shouldn't be a huge step up to fill those roles.
"Sometimes when us old guys move on it helps the younger players develop quicker. It is not always a bad thing, it is just the nature of the sport.
"We are still a young team. You take out Steve and myself and it is a pretty young back line, the next oldest is Morgan Stoddart at 27. That is a big drop, which is only good for the future.
"The big thing is holding onto those players. I know they are contracted for a while which is a good thing."
Following their 20-20 draw with Munster, the Scarlets look set to miss out on the RaboDirect PRO12 play-offs - their only hope is a bonus win against Cardiff Blues while Glasgow fail to get anything against Connacht.
But Lamont insisted he would fight to the end to try and provide a fitting goodbye to the club he has enjoyed a fruitful three years with since his 2009 switch from Northampton.
"It has been a great time for me here," he added. "When I first came down here my career was flagging, I don't think I was in love with rugby as much as I should have been, and coming here has helped me massively, it has reinvigorated me.
"It has been such a tough decision to go. The fans have been great, really positive and I've had some nice comments from supporters stopping me around the town and wishing me the best, which has been great.
"I would have loved to have gone out with some silverware and we will keep going until the end.
"But whatever happens, there is still massive potential in this place."
