Sergio Kindle has impressed at Ravens Training CampThe curious case of Sergio Kindle rolls on in Baltimore.

Baltimore Ravens head coach John Harbaugh told reporters that Kindle is “not a lock [for the 53-man roster],” according to Jason Butt of “[But] he’s done really well and this game will be important for him.”

After astounding John Harbaugh in training camp in early August and showing improvements in the Ravens first preseason game against the Falcons a week later, Kindle didn’t even suit up against the Jaguars. Thursday’s final preseason game in St. Louis could make or break his NFL career.

So far, Kindle’s legacy consists of a freak accident and a DUI. He can turn it around with a solid effort against the Rams.
