Lions coach Jim Caldwell said he's impressed with quarterback Matthew Stafford's approach so far, especially the way he's been absorbing the playbook and paying attention to detail.
"He is getting better," Caldwell told the Detroit News. "His command of the offense has been good."
Caldwell said it was obvious how much work Stafford put in before coming to camp. "I was impressed when he came back that first of all he did not miss a beat," Caldwell said. "He’s a very, very smart guy. You could tell he’s worked at it even during the summer.
"In every facet when he came back, I could see improvement — footwork, accuracy, timing, command of the offense, all of those things. Now we get a chance to see if we can put it together a little bit more, add a few more things, keep progressing and then get some real challenges from our opposition as we start preseason."
