I have one brother who is an Olympic weight-lifting/weight-training coach as you guys know, and another who played at Cincinnati. Both of them have heard about Longo. They consider Longo as a more rounded S&C coach than guys like Mendoza, who they feel is so old school he is an unhelpful dinosaur. That alone tells you that they consider Longo> Mendoza. As to the quality of Longo himself: both their opinions are that he is someone who emphasizes nutrition and general health as much as he does the actual lifting. They see this as a general positive. They were not as familiar with his whole program, but seem to feel that he was not up-to-date on some of the critical "on-your-feet" explosive development training, when he was back at Cincy, but that he seems to be evolving.
My Olympic Coach brother still wonders whether he spends enough time with Core Strength training, and, who knows, this could relate to the hamstring pulls.
Generally, we are dealing with an incomplete data set to make a lot of conclusions, but the signs, both among the profession and the eye-test of our athletes, seem to point to him as a solid 21st century S&C coach. I see no reason to be negative towards Coach Longo. Many of the players themselves say he's made them more competitive, even while saying that they can't wait to get off "Longo Beach".
