The model obviously has limitations as it gave a high probability that Wentz, Watson, and others would be busts, and obviously that wasn't the case.
Are statistics useful? Of course. Should they be relied upon exclusively? Of course not. Is Allen destined to be a bust because of QBASE's model. Of course, not.
I doubt injury risk is in QBASE's model. A player is only valuable when he's on the field.
The Jeter comparison doesn't make much sense, and he failed to get a hit 69% of the time, he didn't strike out 69% of the time.
