Ok, so, to the extent that's some sort of misunderstanding that needs to be railed against, wouldn't it be better to take the fight to someone who was actually clearly perpetuating the misunderstanding rather than to someone who...wasn't? As I said, didn't make sense given the post it was responding to.
If the original post had said anything like what the response suggested it did - i.e. that Cyrus came out of the womb running routes and catching footballs but was forced by evil Coach Saban (lo! doth Saban not care to see his players cultivate the objects of their natural bounty?) to upend the simple WR life he knew and switch to DB, then sure, I guess, "WELL, ACTUALLY..." away at that post if you must. But it didn't. So to the extent one still felt compelled to give a tangential sermon on natural positions and the ambiguity in the word "convert," a better way of doing that might have started more like "Yeah, that's true. But Cyrus wasn't wasn't necessarily a pure WR, and in fact had some experience... and so on."
