Nicely put. That's one of my major qualms as well and you articulated it perfectly. I'd even add Grichuk to your list, I mean sure, he's decent enough but he probably isn't a starter on most contending teams.
I'm just not seeing the overall framework for being a contending team any time soon. As we all know, it takes a lot more than a few blue-chippers to carry a team. I know a lot of people bag on that Tercet guy, but I think he brought up some fair points. A lot of times as fans when we evaluate prospects, we're envisioning them as can't miss big leaguers, but more often than not that doesn't become the case. Which is a big reason why the supporting cast of big-leaguers are so important and aside from Stro, Sanchez and Giles, there isn't a lot to currently like.
