Meyer is listed as 9 pounds heavier than he was on last year's roster. Check back in August to see what his playing weight is then.
Antwon Moore has always been listed as a DB on the roster, but he has always played outside linebacker. If you check his bio, you will see that they call him an outside linebacker. I'm told he is not switching to safety. He had a full shoulder reconstruction after the season -- that requires some extensive rehab, so hoepfully he's ready to go at OLB by August. FWIW, Moore's playing weight is about 10-15 pounds more than what Josh Buhl weighed on his heaviest weigh-in. Of course, Buhl was always listed about 20 pounds heavier than he really was, but Prince puts the players' actual weights on the official site once they've weighed in.
