My plan of letting the strike 80 Put expire for this week didn’t quite work but I made a great roll with the stock at 79.60:

Bought to close TNA 10/05/2018 80.00 Puts @ 0.40 (sold between 0.46 and 0.50 earlier in the week)
Sold TNA 10/12/2018 74.00 Puts @ 0.85 for a 0.45 net Credit and lowered the strike price 6 points with only an additional week until expiration.
