Martinez is the anti controlled racer.
She accelerates and decelerates too often during a race for what seems to be no reason at all. She wanders all over a single lane and changes lanes in many cases for no reason. Once her form starts to break down a bit she's a complete mess and threat to anyone in the race she is near.
She cut off Lauren Johnson yesterday causing Johnson's fall. I think that's at least the 2nd time she's gotten Johnson.
Martinez mentioning that she may stick to the 1500m should strike fear into all of the other women 1500m runners in the US. In the 800m there's less traffic and fewer runners to deal with. In the 1500m positioning with more athletes and for a longer period of time makes her a threat in every race she's in. Not to challenge for the win but to take out as many as she can.
