According to the rule it has to be clear evidence to over turn a call, right? So, one could argue that even though it looked like Workman was safe, it just wasn't clear enough to over turn. Benetti made the argument that this isn't how we've seen it applied to challenges over the season, but if you want to go by the strict rule, then yeah... you could argue that maybe there just wasn't enough there.
So, what about Perez at first? Supposedly there was clear evidence... we haven't seen it, at least not yet. I'll certainly accept that there might be a view that we haven't seen that makes it clear, but I'd sure like to see it.
As for this last one: If I'm just judging by some of the replays, I'd say I'd probably call him safe, but... it certainly isn't perfectly clear. There's no smoking gun there in my opinion that says it's obvious he was safe. It sure seems like they applied that the idea of: "He's probably safe based on what we can think we can see, so overturn it." Which of course ISN'T what they did with the Workman play.
Of course I reserve the right to change my opinion on this if we see better video in the future.
