Yes... Because he clearly said we've had no other great prospects since Dru and Chipper. Some members of this board completely exaggerate comments on this board just so they have something to belittle another poster for no reason.
To be fair, his original point was to dispute this:
I am already on the Blake Rutherford bandwagon. If we can add him and Maitan next year that would be the best 2 hitting prospects we have had since Chipper and Andruw.
Heyward was considered the top prospect in all of baseball at one point, so it probably is accurate to say that Rutherford or Maitan would not necessarily be the best prospects since Chipper/Andruw. Saying that they're the best amateur prospects we have brought in since then is possibly correct though, and the argument got nit picky in a hurry, though.
