Ehhhh I didn't like the call, but he had one foot at 3 yards and one foot at almost 4 yards beyond the LOS. I thought it was a petty call, but the fact that there was a DB in the vicinity trying to cover receivers probably prompted the call. It DEFINITELY wasn't a phantom call. It may have been a picky call and maybe even wrong by a foot or two, but it wasn't completely baseless and made up. OL should know better not to even get close. I think it was just barely a wrong call, but it was very very close.
Another thing to consider is he threw the flag right away, so I'm wondering if the OL had already gone more than 3 yards earlier, but it's off camera and he was just waiting for a pass to throw a flag. We can't see what happened before the throw because the camera is so far back from the LOS where the OL in question were. If the OL goes to 5 yards then comes back to 3 yards before the pass is thrown, it's still a penalty.
All in all, very close. Would need a wider angle to say for sure if it were wrong, but even if it was a bad call, it was super close.
