I'd consider Story at 5 years, $23MM AAV, which was either the MLBTR estimate or the one on Fangraphs.
By the way, I sort of think the $133 million on sportrac isn't unreasonable, although I could see several guys being non-tendered. That's especially true for a guy like Stevenson if an outfielder is brought in as a free agent. So, the Nats are in a position where if, say, $140 million is their max, virtually no one would be brought in. That's certainly possible. However, if they were willing to push the budget up to $170 million, there are several short term signings I think that could help make the team competitive with a break on health, based on the numbers guessed at on MLBTR/FG. This would also give them non-core assets to flip at the deadline if, say, there's nothing out of Ross and Strasburg, Corbin still is not right, and there's no pleasant surprises. That may be most likely, but it also is an if.
