Regardless of whether or not Dozier was a top prospect (and I agree that's a big difference), he hit very well at AA and it sounded like they thought he was ready from a scouting perspective. He was older at the time, and one would have thought that would have allowed him to handle it, maturity wise.
Good point about the Twins not really having success bringing anyone up from anywhere. It's a fair point though they've had more that stuck after a stint in AAA than directly. Whether or not that works for Hicks, who knows, but it's hard for me to trust the Twins judgement about a player being ready. They haven't talked about it with regard to Hicks, but moving Revere would indicate that.
You mentioned that Hicks was more ready defensively, but I'm curious what is it that makes you so confident he's ML ready? Is it the single season in AA, his change in mechanics, the top prospect status he once had where he now gained ground again, or something else you've heard? Would you promote Arcia as well, too?
