Both players were rated top 10 draft picks at the 2012 AFL National Draft, the Demons claiming Viney under the father-son rule with pick No.26, and the duo are strong chances to make their debuts in round one.
However Jones cautioned against getting carried away, aware of how hard it is in the modern game for young talent to make an immediate impact.
"You can't expect guys who are 17 or 18 to come in and dominate midfields, particularly with how the competition is now," Jones said.
"There are a lot of big bodies, and those younger boys need to develop themselves to cope with the rigours and pressures of the game."
Melbourne is well aware of the need to develop the talented youngsters for the long-term. It was part of the reason it picked up experienced players such as David Rodan and Shannon Byrnes during the exchange period and used selection No.52 on the mature-aged Matt Jones.
"Those more senior bodies are obviously going to help them not cop as much of the load," Jones said.
One player who the club will be forced to hold off on playing is Jesse Hogan. Hogan was picked up as a trade incentive selection in a deal with Greater Western Sydney, which gained early picks in exchange for Hogan and Dom Barry.
Hogan just turned 18 and is eligible only to play in the NAB Cup in 2013.
He will train and play for the Casey Scorpions in 2012 but cannot make his senior debut until 2014.
However his performance in the first two rounds of the NAB Cup has everyone at the club excited, including Jones.
Jones knows he has to be patient, but admits he can hardly wait to play alongside the key forward.
"It would be great to have him running around in round one, particularly with the size of him," Jones said.
"It's pretty exciting to see what he could maybe deliver in another year's time, another year in the AFL system and another pre-season."
