1) The season is 6 days away. We will add a corner with experience. Be patient. And when/if we do, our corners all of a sudden look OK. My number 1 choice at this point would be former 1st round pick Willie Middlebrooks- making our CBs: Madison/Howard/Daniels/Middlebrooks/Jackson. Nice young depth for the 3-4-5 and some speed to make up for the lackthereof in Sam and Reggie. And dont forget Poole was NOT put on IR- they expect him back this season, clearly.
2) Edwards has been brutal. I always assumed he would be kept on, just because we had nobody else and he would be a stopgap (like Frerotte, like you mentioned) However, Nick obviously is not going to BS anybody and he will cut you if you are not performing. He will find someone who will at least work hard. Richard was hardly noticeable on the field, and Shaw, while effective, was a backup at best. McGill, based on Jets fans reactions and the interest from 7 other teams, has talent. And like I said earlier, you have no idea what you are getting in Jackson- you may be pleasantly surprised. The personnel staff didnt just pick his name out of a hat, they must have done their homework and believe he can contribute. You want NFL experience? It doesnt always lead to more wins- EXAMPLE: OUR TEAM LAST YEAR! Tons of experience, but very few wins. We must take risks on young guys who may not have the experience but who may just have the skills and ability. They just need a chance, and NS is giving it to them.
If you want a counter argument to your thread title, well you answered your own question. Gus is starting, whether he is 34 or not, because he will give us the... drumroll please for the cliché... best chance to WIN. Sage had a nice little preseason, and I am happy he finally moved up the depth chart, but you cannot tell me that if we fast forward to Sunday at 3 PM, it is halftime and we are down 14-0 with the offense showing nothing, that we will not be chanting GUS! GUS! GUS! GUS! Like the saying goes, the backup QB is always the most popular guy on a football team.
