One thing I discovered last year was the importance of reliable acceleration mechanics.
Upon further reflection, this is a no-brainer, but we struggled all year with one of our guys who just could not/would not start the same way twice.
I’m also going to try to blind/no call pass this year. I suspect it may help the outgoing runner accelerate better since he/she won’t be listening for the call. I think listening may make them hold back a little.
