his calf+ankle injury. he doesn't have much strength in that part of the leg and he is probably having pain/lingering issues. forget about running, watching him throw, his foot work is bad, specially that he doesn't put much weight on his back leg (right leg) when throws before he pivots forward. watch his film early in the season, vs. now. he is leaning on the front leg when he sets and doesn't get much power in his throws which also impacts his accuracy because he is trying to add power with his arm, so sometime it floats, sometimes its too low. he is trying to compensate but the release point is inconsistent at times
the reason I say I don't care much about runnign QBs, is in my opinion, QBs need to be able to throw from the pocket first. Dak had improved and was fantastic at it in early part of season. deadly accurate....throwing in motion or on the run is a plus, it just depends....the scrambling ability to extend plays is key and he has lost that so dependency on OL is higher to keep pocket clean. I looked at his KC, Saints and Raiders games and he was pretty good from the pocket still, less on deeper throws (less power) but pretty average when he was moving specially to his right.....perhaps not enough sample, but compared to earlier in the season when he was very accurate with his throws.
