Wrong. He is a locally good runner that excels at niche events with little to no competition. He fancies himself a storyteller, fitness guru, social influencer, and portrays himself as a positive everyman. The reality is that he is a thin-skinned narcissist promoting himself as a paragon of all manner of virtue much like a televangelist. He is a largely absent father. He treats his wife as an accessory at best and an annoyance at worst. His grasp of the outside world is limited. His nutritional and training acumen are virtually non-existent with his proclamations on both topics being both ill-conceived and borderline dangerous. He is nice on camera but often lashes out against valid criticisms. If you kiss his backside, then he tolerates you. If you challenge him, he gets snarky or he runs away. Seth is all about Seth. His viewers and subscribers, The DGR Family, are just cash contributing rubes and he has very little concern for any of them.
He is not respected by anyone in the footwear industry. His large number of subscribers net him product for reviews but, some manufacturers have started to significantly curtail access to products or just straight up ignore him. His reviews are often non-sensical, arbitrary, and offer very little substantive information for the target consumer. Many brands will bring other YT influencers to product rollouts and trade shows. Guess who doesn't get a press junket? Most product seems to be provided by Runners Warehouse and Seth gets a kick back through an affiliate deal with that retailer for any sales generated by his content.
If you like his whole contrived, hyperactive, and cornpone "Awww...shucks!" act, that's fine. I can see the appeal for many. However, Seth is not an expert on training, injuries, healthy habits, family life, nor is he a particularly talented content creator. He gets some good visuals from time-to-time but most of his output is stream-of-consciousness rambling, verbal diarrhea, fallacies presented as scientific fact, hyping himself, and, as of late, begging for funds while doing utterly pointless product comparisons. Just remember this the next time you find yourself trying to recruit red blood cells, suffering from the inevitable lactic acid attack at the 20 mile mark of a marathon, or trying to replenish your glycogen stores with only nuts, eggs, and salad greens.
