Not to re-hash the exponential re-hashing of paying Romo $14m to be back-up, but I'd like to think we could look back on all of that and see this one lesson for what it will ever matter again since that situation has been so rare... which is...
1) Back-ups are almost never worthy of very much pay because they almost never are able to win games, even the best of them.
2) If you ever found a back-up capable of winning games, you'd be smart to pay him well--as in, starter money--because it's so very common that Starter X is going to be down for some portion of the season, and because the difference between making the post-season and not making the post-season is often only a matter of one or a handful of games.
Hence, I'm not all that concerned, really, about who we get for #2 b/c as others have opined, it's not likely to matter ultimately to the outcome of games no matter who we have back there. And hence... however... it sure would be comforting to think that Tony and Jerry have a verbal pact in the case that Dak's year would end up suddenly like the otherwise healthy Derek Carr's 2016 ended up.
But we'll never know until that moment that we don't want to occur would, in fact, occur.
