I agree signing Ronnie right now is not an issue. IMO if Ronnie has a great year and we need to franchise tag him its not that big an issue since he will be an All-Pro back and paying top dollar for him would be expected.
As for Penny, that is a more delicate issue. If Penny has a year like last year someone is going to offer him big money. No matter how nice a guy Penny is, if he gets a 3-5 year deal making starter money somewhere, like Minny, Tampa or Jax, he is going to take it. Especially Tampa or Jax. Waiting to long to resign him may be a mistake. On the other hand if you think you have the next franchise QB in waiting then its not a big deal. But IMO, if Henne was the next Marino why the heck do you draft White, if you have a Marino (henne) or a Brady, you don't worry about running the wildcat, aka Manning or Brady now, I am not sold on Henne yet,....time will tell.
