Well first, it is pretty easy to sit back and say a rookie CB isn't ready for the prime time.. hell 90% of incoming rookie CB's aren't ready.. nature of the leap from college to the pros.. with extremely different rules at both levels for the corners.. in college they can get away with so much more.
The transition is got to be tough for a seasoned college corner to the pros.. unless they have that rare talent set and played looser at the college level.
Anyway.. Shields being raw is both helpful and harmful to him.. helpful that he doesn't have to unlearn bad habits developed over several seasons in the college level.. but harmful that he just lacks overall experience at the position. However he does have the assistance of falling back on his knowledge of playing receiver as well.. knowing what to look for in route trees and footwork..
Watching him play.. no doubt at times his lack of experience playing corner is very apparent.. but at the same time he has instincts for the spot and speed to recover..
The summation that he isn't ready is probably correct for opening day.. but it is apparent as well that past the top 3 (on on the PUP) that we don't have a more ready option either. That was the disappointment of this camp and preseason.. lack of growth at corner.
I trust Teddy is kicking over stones looking for the answer on the street or in trade.. but with his mantra of going young is going to leave us with little options.. I think it might be time for a one year veteran fill in to bridge the gap for another year and let these youngsters grow a bit more.. or prove that they are never going to fill that spot.
If I have to watch another meltdown with green corners lost on the field in a pivotal game.. I might go off the reservation mentally so to speak.. lol.
