I mean that's not how I'd phrase this. Do I want Ryan in a pressure spot in the 2019 playoffs? Probably not. But that's kind of missing the point. Go look at where Morrow was before he broke out in 2017 statistically. He was 9-10 k/9 with 2-3 bb/9 the two or so years prior. There's a slew of guys who develop in a similar fashion in their 27-28 year range. Strop at 27 had a 7.87/5.02 k/bb per 9.Ryan is fine in low low low pressure.
Like Russell, Almora, Lester type of low pressure.
I would think be caught dead with him up against Bryant, Rizzo, Baez. Runs will happen
He is nice to have in those situations where a mistake is a guy on 1B. Not in the bleachers
My point is more you let him develop into whatever role he gets to over the next few years. if you want to have home grown pitching you have to allow it time to develop.
