Sure there is uncertainty about every player I listed. There is uncertainty about Maybin too. Look at how much his performance has bounced around from year to year. And how often he has missed time due to injury. I also wonder if the dip in his defensive performance this year is a blip or the start of a long-term decline.
Yes. But I'll take Maybin's uncertainties over the others, at least for the time being. If we truly want to compete in 2016-2017, we can't have a giant hole in CF. We know Maybin can get the job done out there. Even if his defense has declined, with his current offense, he's ok as a fill-in piece in RF. And there are reasons to believe his offensive performance this year isn't a fluke. I'll take the guy who has been, at various times, both an above-average defensive and offensive CF over the guys who haven't done anything yet.
I'm not saying don't trade Maybin; I'm just saying, don't trade him for something just to do it. If we can get a guy for him that we think has a chance to be something good down the road or a decent piece within a year or two, then go ahead. But if all you're going to get is a replacement player or C prospect or worse, then don't do it.
