The read
Tarin's aggression and power make her a live threat to end this early, and four of her eight wins have come by knockout.
Aldrich has seen almost everything in her UFC career and has rarely been hurt badly even against harder-hitting opponents, which should serve her well if this goes past the first round.
Lean Aldrich's experience to grind out a decision, with a Tarin knockout the fight's most dangerous alternate outcome.
The matchup
Tarin's aggression and finishing instincts run into a veteran in Aldrich who has been stopped only once in twenty-two professional fights.
Tarin has finished six of her eight wins early, but she has never faced a durable, high-IQ veteran like Aldrich, who has made a career out of surviving early storms and grinding out rounds.
The fight likely turns on whether Tarin's power translates against a much more experienced chin.
