Did some more digging, and came up with this:
Lions | Lehman No. 2 in the Middle
Fri, 5 Aug 2005 05:36:13 -0700
Tom Kowalski, of mlive.com, reports Detroit Lions LB Teddy Lehman is now getting most of his work at middle linebacker. Lehman is in the middle on the No. 2 defense. He spent the early days of training camp getting most of his repetitions at strongside linebacker. Even if Lehman doesn't have a starting position at the beginning of the year, he's expected to see a lot of playing time.
Ourlads also reflects the same info, with Lehman listed at #2 at MLB. Bailey, Holmes, and Davis are listed as starters. That's pretty poor if you ask me. Of course, I haven't received any calls from Matt Millen as of late, lol.
