Yes, but many RP'ers pitch 40-55 innings or 60, so 150-190 is close to quadruple most RP'ers.
I'd like to see Houck and Whitlock stay in the pen and get between 100-120 IP, each.
That would eat up the lost Ottavino and Richards pen innings.
Then, add another RP'er or two to take up the some other IP'd we'd like to see replaced and improved upon.
Trade for one really good pitcher and sign someone like Jon Gray.
