Right, the Dolphins had just went to the Super Bowl. Woodley was the starting quarterback but after he showed he wasn't cutting it any longer, it was time to make the switch. Same thing with Smith and Mahomes. I've already pointed out the dozens of #1 picked quarterbacks that weren't NFL ready. I've also pointed out the numerous reasons as to why they don't succeed. If you have a GOOD team, you can start a rookie right from jump street and he can usually make the transition to the NFL successfully. If you have a good team and a good quarterback, sitting behind that good starter is actually a GOOD thing for the rookie.
