Even ignoring his scores (which are hard to ignore), his role has clearly changed since his "injury" in round 3. His KM have gone way up (base) as Flannos have gone down. His run Meters are much more consistent, adding 4-5 points to his base, and he's still making a decent amount of tackles. With tackles, run metres and kick metres alone, his base is 36 (in the last 4 rounds). Add on the upside of his running game getting TBs, his kicking game getting TAs, and all the added extras, he's hard to overlook even if he doesn't play round 13.
Much more expensive now but in a vacuum it might be the right play.
