Sorry MM, but they are definitely not the same poster. Their writing styles -- and thinking capacities -- are completely different.
swVAHorn writes in coherent, grammatical sentences. EyesonTexas writes (wrote) mostly run-on sentences with other idiosyncratic syntactical features and bizarre punctuation. swVAHorn's posts showed much more critical thought, even when he wrote from anger (when Charlie was coaching); EOT's posts are short, superficial, and impulsive.
Beyond that, they've disagreed on several things. EOT apparently went back and deleted a number of his posts (he's listed as having 188 on this site, but only 156 appear in the search history), but he showed up here as something of an Art Briles apologist (all deleted now), which is about the least accurate description you could give swVAHorn. The differences between them go beyond what someone could plausibly fake.
If their IPs are in some way similar or the same, there are ways that can happen these days (built-in browser VPNs) without two people have anything to do with each other.
BBR, you're right. I got EyesOnTexas crossed with swVAHorn. EyesOnTexas and OrangeDKR are on in the same. My mistake.
