Are you serious?

Saying someone would be a 5-tool player “at worst” is almost always a silly thing to say and in this case it is a REALLY silly thing to say.

Ackley, of all players, is not a guy who everyone is sure of his 5 tools on.
He obviously has plus speed and obviously has a plus-plus-plus-plus-(a thousand times plus) contact hit tool.
No doubt about that.

All those other tools are in question.

Except for a little bit of his freshman year of college Dustin Ackley has never been a corner outfielder. Ever.
Why? Partly team needs (until this year) but also because his arm is made of jelly and has gone under the knife a bit.
Poor arm health which has lead to an inability to throw well is a major reason his college career has come at first base.
So… No. He isn’t “at worst” a 5 tool player. Because.. at worst.. his arm turns out so bad (late-career Jeff Bagwell) he can’t even throw from LF.

Also. His power is also a big question mark. If he is limited to 1b/LF at the MLB level he is probably going to have below-avg power for his position.
Hes a great hitter, with amazing wrists and wonderful batspeed, but he isn’t a very big guy and hasn’t really been a big slugger even with the metal bats. He hits tons of doubles and is tied for the team lead in HRs this year but he has never been a guy that was really a lock to have MLB power. In fact, one of the biggest marks AGAINST Ackley is whether he will have MLB power… esp if he is a 1b/of only.

Also, since his arm and future position are both big question marks right now it seems premature to give him an average or better grade in the “defense” part of the tool grades.

So basically… “At worst” he is a player with 2 plus tools and 3 weak tools.
That is a far cry from "at worst Dustin Ackley is a 5-tool corner OF.

The arm thing is what really blows my mind about the “5-tool” thing. When on earth has it ever, ever been said that Ackley was a plus thrower? Where did you see that?
In HS that might have been true (he was a good pitcher) but since he became a prospect at UNC his arm has been a Q the whole time, due to arm health reasons.

Don’t get me wrong. I love Ackley. He is an amazing, amazing hitter and a great ballplayer but he isn’t necessarily a 5-tool players.
But, heck, the real great thing about him is that he is so good that he doesn’t even HAVE to be a 5-tool player to be a good MLB ballplayer. Plus speed and plus-plus hitting for avg will go a long way.
