Is it though? I remember watching Morgan read the safety on every play and throwing daggers across the middle whenever it looked like they were going to come in on run support. I remember Minnesota checking to deep passes whenever a subpar corner was left on an island.
None of those things are happening right now. He's throwing his receivers into the safety, throwing deep into double / triple coverage, etc. Those were things we didn't see in KC's offense. Honestly, his throwing motion even looks worse than it was two years ago.
I'll admit, I'm biased. I thought Sanford was a bad hire. The offenses and quarterbacks he works with seem to get worse with time, not better. Think given the offensive line play today, there's a chance that we might have seen the last of him.
