What's missing from too many of these assessments is that the job of a 1-tech is so very unglamourous, and second, that few rookies at any position ever are so impressive that they're instantly regarded as high impact assets.
Rush to judgment is a thing, and it's especially a thing among football and basketball fans. (Baseball fans have always had patience imposed upon them by the minor league gauntlet... but forced or not, at least there is practically zero baseball fans right now getting worked up that their first round pick is taking some time acclimating to a higher level of the game than they've ever played before.)
Some people just look for things to complain about. Some people have no patience.
Some people check both those boxes.
