We could say the same of any draft pick as there is no such thing as a "sure thing", and yes that means even the chosen one that is known as Royce. But I have to ask, and yes I know I will regret this... but what the heck does that even mean? Do you not like the fact that his obligation to his country has prohibited him, until now, to throw lots of innings in the minors?
The guys has loads of talent given his high draft status and for you to so cavalierly sit there and declare him "not a prospect" because of his "advanced age" of 23 years and lack of innings thus far... well you'll have to excuse me for coming to the defense of my fellow brothers in arms.
In closing, I apologize in advance if I misinterpreted your statement, if I did not... please do not speak ill of those who serve. It does not sit well with me.
This came up when the Twins drafted him. The assumption was that he could serve his two years of service in the reserves and still pitch full time for the Twins. It was a risk since those rules could be - and were - changed. So the Twins thought they'd have Jax around a lot more when the drafted him. If he could have played with the Twins, he was a solid 3rd round pick. But because he's missed so much time, it's really hurt him.
Sure, there are no sure things in the drafts but it's always better to bet on players who are actually playing baseball, like Lewis. Right now, Jax hasn't played much. When he has, he hasn't actually been all that dominant (I made the comparison to Stewart for a reason - Stewart is getting raked over the coals for his low K-totals in AA, Jax has worse K totals in low A). He's old for a prospect. Sure, there are old players who figured it out but it's not a thing you want to rely on.
Lastly, this is a minor league baseball forum. We're talking about players in our system. Occasionally, we get feel-good stories here, especially from Seth. But generally this is about talking about these guys as prospects. There are a lot of really good guys in the minors who won't make it and only occasionally is that mentioned. I don't think you should expect people to not say what they think about Jax the prospect just b/c you might be overly sensitive to it. Saying a guy with his profile isn't really a prospect anymore isn't that controversial.
