Last year, No. 2 overall draft pick Dustin Ackley was good just about all the time. Break down his numbers any way you want, and he looked like a stud. When you post an OPS in the 1.300 range, that's how it tends to work.
He wasn't quite so good on Friday nights, with a slash line of .397/.493/.586 in about 70 plate appearances. Maybe not on par with his overall numbers, but still excellent by any reasonable standard.
And to many draft watchers, Friday night stats matter. Because college teams usually play four or five games per week, with important conference matchups on the weekends, aces typically face off on Fridays (as described by Jeff Bradley in ESPN The Magazine).
