Good for him to get the experience I guess, also never rule out terrible teams making terrible choices. Dorsey is coming along as a 1st year play caller but I'd think you'd want him to have a bit more experience doing that before calling him up.
I will say they probably weren't practicing today anyway but it's not a great sign though maybe they're just trying to look like they're taking it seriously. Either way though coming back after being out for multiple weeks isn't easy either.
