Their manager would certainly be trying something different and giving more chances if he was in a relegation fight....
In fairness, Heaps is currently considered one of the worst managers in MLS, and a LOT of Revs fans want him gone.
But it's not like Wright is fighting for his spot against geriatrics. In the positions he can play (forward/wing):
Juan Agudelo is 24, just two years older than Wright, and has been capped for the USMNT.
Diego Fagundez is the same age as Wright. Only he has 4-5 years of first-team experience.
Kelyn Rowe is 25 and recently played for the USMNT at the Gold Cup.
Femi Hollinger-Janzen, who's deployed in the supersub role, is 23.
As for the "he'd change things up if he were in a relegation battle" bit...um, I'm pretty sure that signing a player who is proven MLS quality and has played in a major international tournament (Euro 2016, with Hungary) counts as changing something up. Németh scored 11 goals in 28 matches for KC in 2015, and KC has sorely missed having him to pick up some of the scoring load.
That said, at least loan him out or something so he gets playing time. If he's not on the bench or in the 18 it's not going to help him develop.
This is one of many areas where the Revs are sorely behind other MLS teams: they don't actually have a USL affiliate where they can get their homegrowns and draft picks match time. They have an "affiliation" with Rochester, but never use it, partially because Rochester is to USL what the Chicago Wolves are to the AHL (basically, a fiercely independent team that cares more about winning than player development, and does have the 2015 USL Cup to back that up).
All around them, MLS teams have USL affiliates where draftees, homegrowns, and even academy kids play against pro opposition. Philadelphia has Bethlehem, Houston has Rio Grande Valley*, San Jose has Reno*, KC has Swope Park Rangers, Salt Lake has Real Monarchs SLC (ugh, what a dreadful name - fantastic team though, they're first in USL right now), and of course the various "2" and "B" sides (Orlando, Toronto, LA, Seattle, Portland, Vancouver, NYRB).
* - These two are a bit different, because while they're owned by different people than the MLS side, the MLS side controls the technical staff.
That leaves New England, Columbus, Dallas, DC, Chicago, Minnesota, Atlanta, Montréal, and Colorado out in the cold and affiliating with otherwise independent teams. Of those, Minnesota and Atlanta are brand-new sides so they have an excuse, and Dallas (who uses a bunch of youngsters anyway) and DC intend on launching teams in the near future. Columbus, Chicago, and Montréal have all at least made *some* use out of their affiliates (Montréal actually shut down their B team in the winter). That leaves New England alongside Colorado, a team that is also horribly run (Stan Kroenke teams gonna Stan Kroenke teams).
TL;DR: The Revs organization is stuck in MLS 1.0, Jay Heaps is an awful manager, he needs to get away from there and to somewhere he can get playing time, even if it's in the USL.
