Spoke to Oglemi. Murkrow is being taken off the list for now.
Phanpy can also do this. =P
Edit: I also support the Murkrow getting an analysis.
Mostly outclassed, not totally outclassed. Heracross does have better coverage, as well as a little more bulk. However, Sturdy allows Sawk to survive hits at full HP that it normally wouldn't, and that can sometimes mean the difference between winning and losing. It's not the most important advantage in the world, but nevertheless one that should be considered.Sawk is outclassed by Heracross, but I do agree with Gardevoir.
Using a 252 HP / 252 Def+ spread, Erufuun hits the following defensive tiers:
Physical - 120.3
Special - 115.5
Using the same spread, Evolution Stone Monmen hits the following defensive tiers:
Physical - 121.0
Special - 115.1
Sample calcs to better illustrate that.
Garchomp 252 Atk Outrage vs 252/252+ Erufuun = 48% - 57%
Garchomp 252 Atk Outrage vs 252/252+ Monmen = 45% - 53%
Latios 252 SpA Draco Meteor vs 252/0 Erufuun = 89% - 105%
Latios 252 SpA Draco Meteor vs 252/0 Monmen = 92% - 109%
The difference in bulk is minimal, and when you consider that Erufuun can hold Leftovers I'd say that Erufuun gets the nod in terms of bulkiness. Leftovers also nullifies any advantage that Monmen has in terms of Leech Seed healing.
Taking less damage from Gyro Ball is nice but you also lose the ability to do things like Encore Scizor's Swords Dance before he uses Bullet Punch or Breloom's Swords Dance before he uses Mach Punch.
I'm leaning towards Erufuun > Monmen.
