Dak Prescott is a warrior, pure and simple. The team likes him and plays for him more often than not. He was the same player at MS ST. He will give effort and has tremendous determination. I have always liked the kid and will continue to. He has issues in the pocket and progressing through his reads. I truly hope someone can assist him in overcoming these. They will (have) hurt us significantly in the past and will again. That, in itself isn't a reason to "hate" on him and, with the exception of a few here, I really don't think that's the problem.
There are a lot of us here who've watched football a Loooooong time and we see things differently from many. Personally, what I comment on is what "might" be if he can work through his penchant for taking too long to let it go, extremely suspect pocket awareness, ball security and, untimely errant passes. Not to say that everyone doesn't have those issues come up once, maybe twice in a game - but it's something that is keeping Dak from being potentially a very, very good QB.
As far as "haters", I believe that's a catch-phrase for the under 40's who just like to lump people into categories rather than taking time to actually consider an alternative perspective and participate in an intelligent and constructive conversation.
