Frazier has all the tools you'd want in a top of the draft talent.

While not being a hulk or a projectable athlete, Frazier gets your attention quickly on the field. At 6'1", 190, there isn't a lot of good growth left in Frazier. He is already a strong, well-built athlete so any future growth will just cut into his future ability to stay in center field.
Everything you have read about gritty players can be said about Frazier. The difference is everything you've heard about 5 tool players can be said as well. He has a plus arm, plus-plus speed and is a lock to stay in CF as long as he doesn't gain 25 pounds soon.
His hitting ability is very good. It isn't a prototypical approach and he could iron out a few minor things like using his legs a little more, but his talent will let him succeed while he works on these things. He has massive forearms that create incredible bat speed that can launch balls 400' with the flick of his wrists. His power won't be crazy but 25 homers isn't out of the question.
Looking at the fire-haired burner, it's easy to see a future star. He has all the tools, the drive and should be one of the first picks in the draft. Potential hiccups could be durability and outgrowing center field but he should be a very good MLB player with a chance to be a star.
