I really don't see the logic in sticking with Brock. He was terrible. He wasn't fine. He couldn't hit the open receivers, he should have had about 5 picks instead of 2, luckily the Eagles CBs can't catch. His deep passes were a joke. He didn't avoid the rush any better than Siemian. 

If Lynch isn't ready then go ahead and put Siemian back in. Brock sure didn't bring a spark and Siemian is probably a better QB. Brock is in his 6th year, do they really think he is going to magically improve now. 

Lynch needs to be given a shot. Even if he fails, let him learn failing, and develop a feel for the NFL. Besides the Patriots have a harder time defending against a mobile QB. Lynch is by far the most mobile QB Denver has.
