Well, two things about that.
1. The refs are also able to (and often do) use judgement on some of these hits and subsequent calls. The penalty in question - the hit against Baker - is the one I found incredulous. The tackler used good form, lowered his head in order to wrap up, and *barely* grazed Baker's face-mask in the process. We have ALL seen worse hits not called - including as recently as yesterday - and cleaner hits with perfect form ... called RTP by the refs. So yeah, there is room for discussion on this if the refs are going to continue to be inconsistent in their rulings.
2. The Tweet in question was posed by Rich Eisen who explicitly asked for "thoughts" on the call. So I gave mine.
Like I said it was probably the angle that made the ref throw the flag, if another ref was posted back thee he may have been able to say no go. Again, it was a missed call. So it doesn't, IMO, fall under a consistency thing other than refs miss calls consistently and particularly in the backfield where half or more of the players are and there is only one guy watching.
The tackler lowering his head is where he got himself into a pickle. He put the crown of his helmet into play. Had he not done that a flag doesn't get thrown.
Missed call, but it happens a lot. It doesn't have anything to do with the rule really, it has to do with the ref having a bad angle IMO. This wasn't a judgement call it was a missed call.
