Here are the highlights of this week's chat with Post-Dispatch readers.
Q: When do sample sizes expire for Justin Williams, Lane Thomas and Tyler Webb?
A: Sample sizes on Thomas and Webb are sufficient. When you see Williams turn around Trevor Bauer at 115 mph (Monday), that's impressive power. There's some talent in Williams, although no consistency yet. He also has the best throwing arm in the Cardinals outfield, so he's a keeper, but probably not as a regular.
