"Come on, Blue, let's talk, let's talk!" Brandon Knight was imploring his teammates to communicate on defense as he settled into a defensive stance Thursday in the second half of the Pistons-Celtics summer league game in the Magic practice facility at the Amway Center. It was another example of Knight's growth as he enters his second season. One goal this week for Knight was to become a more vocal leader for the Pistons and, by all accounts, that has occurred.
