If you were wondering why Hop was waving his arm like a chicken wing... thats a safety over the top call
that clip where Kyler and Hop were face to face on the last drive, Kyler scratching his nose and Hop says OK..... thats changing the safety over the top call from the "chicken wing" to the "nose scratch"
chicken wing had been used, change the signal and move on... Now if you see Dhop nose scratch, look for a throw anywhere other than Hop
