Since the axis of evil is addressing me all at once I'll answer is kind...
Show me the team in the NFL that CAN recover from injury and still win a Super Bowl, the short answer is that there isn't one, the Ravens got healthy and went streaking at just the right time.
No team has All Pro caliber players sitting in waiting for the vets in front of them to go down, if they were that good they would already be playing, there are 32 teams in a "win now" league (as you guys are most assuredly proving with this thread), there's not a lot of room or time to develop or mold players on a bench, teams take players who can help them now. No team can recover from numerous injuries and win. We were one Rodney Harrison broken forearm away from going to another Super Bowl in 2006, injuries happen, this is football.
We've still been in 5 Super Bowls since 2001 and won 3. You can't expect us to sneak up on teams like those early 2000 teams, moreover we've been picking from the bottom of the draft since that time. Yet there are 31 other teams that would leap at the chance to acquire Gronk (taken instead of Matthews) Hernandez, Wilfork, Mankins, Mayo, all of our runningbacks and even Jones and Hightower who will end up being solid players. We've always had role players; Patrick Pass, the Aikens, Antwan Harris, JR Redmond, Jermaine Wiggens, they may not have been Pro Bowl players but they've helped us win, we may not have won without their contributions.
Teams devoid of talent don't win, that's why when BB arrived they went 5-11, all the coaching in the world wouldn't have helped them, they needed those draft classes in 2000 and 2001 (Brady, Seymour, Light) and beyond to put them over the top.
This goes back to the draft "experts" on this forum, hindsight is your best friend. I'd suggest you take Babe and myself up on our offer to create a draft day thread and submit your picks in real time to see, when you're on the clock, actually picking from a round and pool of available players, that you are still the expert that you think you are?
What you'll find is that the draft is an inexact science and when you're relying on people its even more tenuous.
