Nah he's been on Stroman's ass since we first heard reports of how he was prepping to come join the rotation back in August. He's been just as skeptical as one could be, has said numerous times that he should be in the bullpen and not in the rotation, even now, tried to justify Stroman not being in the top 4 rotation for the playoffs just last week, and tries to go out of his way to overly critique Stroman's starts.
As for your second paragraph, Stroman is having his dead arm period right now already, his 4-seamer is still 2-3 mph slower than where it was in mid-season last year. He's been throwing low 90s, topping at 93, when last year he was hitting 96/97 mid-way through his starts.
