To be fair to Jim, in 2010, Morrow was on pace for 5 WAR/200 innings, 3.6 WAR/200 in 2011 and 3.9 WAR/200 innings in 2012. That's basically the same as Stroman in 2014, 2016, 2017. I think those are #1/#2 numbers.
That said - I think it's a stretch to think Morrow would still be a top of the rotation guy in 2018.
