That was Randy Johnson's issue for the first part of his career. He was extremely wild because he couldn't replicate a consistent pitching motion to keep the ball around the strike zone.
Stroman is younger than Price and Greinke and I'd think be a safer gamble. There is always going to be risk acquiring a pitcher, but if the O's do plan to be competitive in 2023-25, then I don't see how it happens without acquiring any starting pitchers.
I don't it matters unless he goes out and puts up a 1.000+ OPS and slams like seven homers while stealing a dozen bags. It has to be something massive to have really any impact. (Or he could get like a dozen hits--all singles--in 100 ABs which would may have some sway in the opposite direction).
Barring something extreme, I expect he will compete with Urias and Jones (along with a free agent like a Galvis type) for ABs in the infield. Personally, I'd like to see both him and Urias get near everyday reps for at least the first half of the season until they either prove themselves or Westburg or Vavra is ready to take their place.
