I got this from the Panthers blog. If you follow the links, you can get some very interesting information about current QBs in the NFL and the incoming prospects. The really interesting stuff is about Ricky Stanzi. But one thing that really stood out was this: "3+ red-flags is almost guaranteed a bust in our system (3+ red-flag QB examples in our system = Ryan Leaf, Tim Tebow, Chad Henne, Max Hall, Rex Grossman, Derek Anderson and Tavaris Jackson...among others. Jay Cutler is the probably the best NFL QB with 3+ red-flags in our system). "
