That's Lillyman v Seumanufagai over the past 4 and a bit seasons (all of Ava's career, and the corresponding time for Lillyman). Even then, not really comparing apples with apples as Lillyman is on a gradual downward curve, while Ava is improving (including the only significant advantage Jake's numbers have here - his minutes per game... Ava averaged 41 minutes last year, without dropoff in per-minute output).
Really similar shape, Ava probably actually slightly better than I thought before putting them directly side by side.
TALbA = Tries, Linebreaks & Assists per 80 minutes
EPC = Errors & Penalties conceded per 80 minutes
TbOff = Tackle Breaks & Offloads per 80 minutes
(m80 is nothing, just a factor cell to avoid repeating equations)
Lillyman = Blue
Seumanufagai = Green
The rest should be fairly explanatory.
Seems like a really solid option to strengthen the stocks - so long as the price is decent.
