I think Jerry Meyer is pretty credible. I know for a fact that he attends many events and talks to coaches and recruits, but more importantly, he is at a leadership position with one of the biggest conglomerate recruiting networks. So he has access and input from the largest number of sources. That is a huge advantage, it does not mean that everyone of his picks is just his own opinion and source.
People are misinterpreting the picks as well. It is a marketing tool, but it does not necessarily mean that the recruit will end up there. It means that based on available information, that is where the analyst believes the recruit would end up IF the recruitment ended at the time the pick was made. Jerry Meyer obviously has an unfair advantage due to his network, but he is much better than others.
I am not saying he is not credible or he doesn't have connections I'm just saying I tend to follow the teams recruiting guys more because they are following 15-25 kids recruitment's and not 300+ recruitment's.
