Recently-signed Lions OT Jon Jansen will compete with Gosder Cherilus, last year's first-round pick, at right tackle, though he might cross-train at other positions. Jansen has been a right tackle his entire career and fits what the Lions want to do in the power running game. He has struggled with injuries the past five years, but the Lions think he can still be an effective player. "We've all had situations where a player's come available, and you can't believe it," coach Jim Schwartz said. " 'Whoa, how did he become available?' And then you watch tape, and he doesn't look like he did five years ago, something like that. We felt very comfortable with him that he's looked like he has. He has had injuries over the past few years, but he's also played productively and played at a high level when he's been healthy."
