I don't think Gigabytes would go to Cleveland. Any lingering interest to keep playing would be squashed, if this were the only option.
.. and there was pre-game chatter from announcers, kcc.. about Andy's conversation. It was weeks ago, and was to Jon Gruden, iirc. The relayed quote was something along the lines of Andy saying, "Alex is my guy, and he can be with me until I retire."
.. but that doesn't necessarily have to translate into "I want him as my starting QB forever!" Could be he just wants to instantly hire Alex as a coordinator, when Smith hangs em up.
