I will list for you a few players (mainly from Randwick for obvious reasons) that I have seen in the last few years that haven't got a lot of time or much development simply because there is no space for development in Super Rugby squads. These are players with huge talent but just haven't blossomed immediately, they needed more work and more high level game time, in some cases arrived with a roar and then faded to be discarded. If depth was a problem they should be at that next tier.
AJ Gilbert (7)
Selala Lam (6,8,7)
John Fonokofalafi (Hooker)
Clinton Sills (Winger/13)
Lotu Taukeaiho (Prop)
There you go, some aren't recent, as in this year, but that is just off the top of my head in a couple of minutes.
Sorry for the late reply but could not let this go
AJ Gilbert signed for and was part of the Reds squad in 2008. He was a George Smith lookalike with the dreadlocks, ironically caught up in a crap QLD time behind Roe and Croft and was replaced by Daniel Braid.
Clinton Sills spent at least one year in the Brumbies Academy with a professional contract.
Lam as well was part of the Brumbies Academy. Sometimes when you drop from the Waratahs world you do not fall off the world.
However I believe the Waratahs have taken to shiny and new and discard quickly. Tom Kingston may be one like Mark Gerard.
There is also quite very players who have taken their time to develop and at their third franchise before they broke through.
S. Timani started at Force and Brumbies before blossoming as a Tah.
P. Betham signed from school by Brumbies at the same time as Kurtley Beale and was indifferent at the Rebels but ITM cup now blossomed as a Tah
Ben Mowen - Qld junior 1 Reds game, reasonable at Tah and blossomed Brumbies
Scott Fardy late bloomer.
