Folty showed great improvement last year. Why at this time would anyone consider anything other than a starting pitcher. There are probably at most 20 pitchers in all of baseball that have hte stuff of Folty. Doesn't mean anything but man give it some time.
Folty - 0.4 career WAR, 1.4 WAR in 2016 - 25 years, 150 days
More successful (many significantly) at a similar age...
Shelby Miller - 8.5 career WAR, -0.8 WAR in 2016 - 26 years, 147 days
Aaron Sanchez - 7.8 career WAR, 4.7 WAR in 2016 - 24 years, 248 days
Marcus Stroman - 4.8 career WAR, 1.5 WAR in 2016 - 25 years, 309 days
Jon Gray - 2.5 career WAR, 2.3 WAR in 2016 - 25 years, 121 days
Carlos Martinez - 9.8 career WAR, 5.9 WAR in 2016 - 25 years, 166 days
Noah Syndergaard - 8.5 career WAR, 6.0 WAR in 2016 - 24 years, 189 days
Gerrit Cole - 9.4 career WAR, 1.9 WAR in 2016 - 26 years, 179 days
Sean Manaea - 2.7 career WAR, 2.7 WAR in 2016 - 25 years, 33 days
Dylan Bundy - 1.8 career WAR, 1.7 WAR in 2016 - 24 years, 111 days
Kevin Gausman - 6.2 career WAR, 4.2 WAR in 2016 - 26 years, 59 days
Michael Fulmer - 4.8 career WAR, 4.8 WAR in 2016 - 23 years, 356 days
Lance McCullers - 4.0 career WAR, 1.7 WAR in 2016 - 23 years, 155 days
Carlos Rodon - 3.0 career WAR, 1.5 WAR in 2016 - 24 years, 86 days
Yordano Ventura - 7.2 career WAR, 1.9 WAR in 2016 - 25 years, 233 days (when he passed)
Chris Archer, Jake Odorizzi, Alex Cobb, Carlos Carrasco, Danny Salazar, Sonny Gray, Garrett Richards, James Paxton, Drew Smyly ALL had more success before they were Folty's age.
I honestly can't say for sure that I'd rather have Folty than any of those names at this point. Can you?
Again, we're all pulling for him - the point is he's not going to be a "cheap, young starter" much longer. It's time for him to quit hanging his head and acting like it's somebody else's fault that he's not successful.
