Here's a blast from the not-so-distant past:

Kenyatta Walker. Remember him?

Well, according to the Charlotte Observer, the former Bucs right tackle reportedly in Charlotte for a free agent visit with the Panthers, with whom he had some heated exchanges while playing for the Bucs. Walker was released after the season and is coming off a very involved knee surgery. He has since been replaced here by Jeremy Trueblood. In Carolina, Walker, a former first-round pick, would be used as a backup to starting tackles Travelle Wharton on the left and Jordan Gross on the right.

You may remember Walker's well-documented run-ins with Panthers defensive end Julius Peppers and Walker's infamous false starts in games against the Panthers. Those could make for an interesting subplot if Walker signs on.
