i watched pretty much all his games last season, i definitely like him.
although, much of that doesnt relate to fantasy. i really like him defensively in right. nice speed/range in RF, especially for a bigger guy. excellent arm.
offensively hes definitely got a lot of pop in his bat, but before id take him for fantasy hes got to prove he can hit for average at the mlb level. he strikes out a ton, which is fine if he can maintain hit .275 or so (.287 minor league career).
in his only full month in the lineup in september he was getting it together.
if he does hit for enough average to stay in the lineup all year, i think 20 homeruns is the lowest end of his projection, more like 25.
10-15 stolen bases is reasonable given showalters not the manager anymore and his decent minor league record.
so yeah.. i like him, but not quite yet for fantasy.
i might grab him in the last round or two, bench him and see how he starts off.
