No doubt. However, all three of Touki, Newcomb, and Sims could be front line starters if they can fix their control issues and continue to develop. I don't get why some guys like that have a number 3 starter ceiling put on them.
Longenhagen for FG just pegged Gohara with 2/3 SP upside.
Here is the type of praise they heap on future Aces"
"Giolito has the highest ceiling among Minor League pitchers, boasting an elite fastball that sits mid-to-upper-90s and a 12-to-6 curveball that he throws with power and hard, downer action. His changeup has steadily improved in the past two seasons and his confidence along with it, giving him a legitimate weapon against left-handed hitters."
"The big right-hander has serious swing-and-miss stuff, with a fastball that touches the mid-90s consistently and can hit triple digits to complement a devastating power curveball. Unlike some young pitchers, Reyes is willing to throw his changeup and understands the value of having it to make his two plus offerings better. Though it's behind the other two, it should be Major League average in time.
Command and control have been Reyes' biggest obstacles, but he's improved tremendously over the past couple of seasons, particularly in terms of his fastball command."
"His stuff is ready to get big league hitters out, starting with a mid-to-upper-90s fastball that gets swings and misses both in and out of the strike zone. When Glasnow returned from an ankle injury in 2015, his feel for his curveball was inconsistent, forcing him to throw his changeup more and helping him improve his third offering. Control has always been his biggest issue, but he's made significant strides in that area. "
Notice a trend? Huge fastball, elite breaking ball, a change that is already showing results, and command that is already coming together. These are not guys with a good fastball/curve combo with the potential to add a change and poor command. These are guys with 3 plus or better pitches and demonstrated command.
