Training camp is here. They allow tackling there and everything. Around the League will count down the top 30 position battles to watch throughout the preseason.
•This battle wasn't on my original list. Wells is coming of a career-best season and Williams hasn't taken an NFL snap. And then I saw that Wells was placed on the active/PUP list to start training camp. Williams, coming off a torn patella tendon, is healthy enough to start camp on time.
•Wells originally said he had "just a scope" on his knee. That was six months ago. Eventually, he conceded the procedure was a little more complicated. Ken Whisenhunt tried to push Wells along in his recovery.
"(Wells) has got to bust his tail the next few weeks to be ready for training camp because some guys have looked good there," Whisenhunt said in June.
• This is a good problem for the Cardinals to have. They should be careful not to rely on Williams too much coming off such serious injury.
