My understanding is that the Lions will keep Moore this season, but they certainly have a comfort level with Germane Crowell and Johnny Morton. If he is released, the Jets would be an obvious candidate, but I think he'd get some interest other places, too. The Colts' defense still has some soft spots, but overall I think the Colts will make another strong run this year. Peyton Manning is the best QB in the game, and he's going to get better. No, but I do believe the Bears will make a playoff run this year.
Serious contention is probably a year away.
I know the Bears are very encouraged by Cade McNown and Curtis Enis this offseason, and I love them drafting Brian Urlacher, signing Phillip Daniels , etc. You probably know that Joe Theismann is picking the Bears to win the NFC Central. Mort, The Raiders have done a great job over the last couple seasons becoming a real contender for the upcoming year. The loss of Willie Shaw, I'm not sure what it means. I haven't paid attention on the OLB, but Porter is a terrific talent but considered a project, so I would be mildly surprised if he became a starter as a rookie.
