I saw you two were disputing the decision so tonight I sat down with a coffee, glass of milk and pen and paper and took a look at it with no sound.
Notes:
R1: 10-9 to JDS - better stand up, clinch fighting and takedown defence.
R2: 10-10, possibly 10-9 to Miocic. JDS better clinch fighting and takedown defence.
R3: 10-9 to JDS - reversal and knockdown
R4: 10-9 to JDS - stand up and takedown.
R5: 10-10 - possibly 10-9 to JDS due to clinch fighting.
JDS had the better standing. A lot of Miocic's takedown attempts were defensive ie. Miocic would get worried that JDS was winning the stand up, then Miocic would take the shot and JDS would stuff it or reverse it. Easy to attempt a takedown on JDS as he stands within Boxing range, but he would stuff it everytime almost.
