Yeah a major college program SS won’t have a spot to play on defense. Sure
All we can go on is what we have available to us. I'm more than willing to admit the Braves have far more information. That doesn't mean they're automatically correct and that we shouldn't even discuss the picks.
As for Shewmake, it's difficult to project him at any position.
We can rule out catcher immediately.
First is unlikely. I don't think anyone expects him to do anything more than potentially back up at first.
Third is possible but his arm isn't his best tool. There's doubt he has the arm to stick at short so playing third might be a stretch.
His natural position is SS but again, everywhere I've read speculates he'll be moved. He's 6-4 and the Braves want him to add weight to increase his power. His range is already not exceptional. If he adds weight and loses a step, add in his average arm and he's not really likely to stick at SS.
Second is a possibility. However, 6-4 is big for a second baseman. If he stays wirey and never really adds power, I could definitely see him as a Craig Counsell type second baseman. If he bulks up, he might just be too big for second.
The OF is probably most likely. If he adds bulk and gets 15 HR power, I could see him being a Nick Markakis-like OF. Maybe not exceptional but certainly with value.
Ultimately, if his bat is exceptional he'll be able to play enough defense to stick somewhere. However, I can see why people think being a utility player might be his best bet. His bat doesn't really profile for a corner OF, his defense doesn't really profile as a starter at a lot of places. But he's likely to be able to play competently at a number of spots and has a much, much better bat than your average backup.
There's a reason that even the Braves mentioned the word "Utility" when talking about his future. A Mark Derosa super-sub type is definitely a possibility. That might justify using our 21st pick on him. However, I still don't see why he got slot.
