But, with the World Cup in New Zealand only 13 months away, McBryde has dismissed any fears he will struggle to cope with the increased demands.
"I believe there are three types of people in the world; those who like to make things happen, those who watch things happen and those who wonder what is happening?" said the 40-year-old who toured Australia with the Lions nine years ago.
"I've probably been in all three categories at some stage of my life but I'm a hands-on person and I like to get my hands dirty and roll my sleeves up.
"I may get criticism for taking on the role but I'm confident in my ability. It's a healthy opportunity and the right move for me to make.
"I would have been more comfortable had I not taken up the role and stayed in my comfort zone. But I've never done that and I won't start now.
"I hope the weekly challenge will make me a better all-round coach and be of benefit to everyone.
"From a national perspective, Warren (Gatland) is the forwards orientated coach so he can link up with the other coaches for feedback. So this will allow me to expand on my role and get my teeth into working with young players at regional level."
Former Llanelli and Scarlets captain McBryde made 250 appearances for the club between 1994 and 2005.
And he believes he can follow in the footsteps of 2009 Lions coach Shaun Edwards who shares his time between Wales and London Wasps.
"Shaun has managed to juggle the two but it's not a role which suits everyone," added McBryde.
"You have to have a certain type of personality to forfill both roles and I know it will be hard work. But until I put myself in that position, I will never know."
McBryde joined the Scarlets coaching staff after retiring from the Llanelli-based outfit but was appointed Wales forwards coach by Gareth Jenkins in 2006.
Gatland retained McBryde who was part of the 2008 Grand Slam coaching team before he then led Wales on their North America tour a year later when Gatland, Edwards and Rob Howley were on duty with the Lions.
And the Scarlets, who finished second bottom in the Magners League last season, insist his acquisition is a major coup.
"We are clear with Robin's commitments and we know exactly where they lie," said Davies.
"He will be with us for the vast majority of time but leading into and during major events with Wales, he will be with them.
"It was important in a situation like this which could prove tricky that we outlined it from the start. Everyone is happy and agreed to it.
"Robin has great experience at international level and I'm excited to see him guide our forward pack this season."
