I personally like Ryan Tannehill.
I couldn't see calling Marino DM1
When my son was a pup, we were watching a game in which Marino threw back-to-back interceptions against the Patriots and the second resulted in a pic-6...the sandwich I was eating accidentally fell out of my hand and landed on the TV screen as I yelled "Damn" Marino...became the nickname my kid called him by from then on. Despite my best attempts my kid became a Raiders fan. Karma's a bitch!
As for a nickname, I am with you...his name sounds just fine to me.
