This argument is circular logic. You're saying they need to prove they are willing to spend by spending money. If that were indeed a hang up for players why would Lester sign here to begin with? And logically if they have the ability to sign Lester what's stopping them from having the ability to sign <x> player 2 years from now? Again, you're welcome to your opinion but in my opinion players will go to a team that A) is willing to pay them the most and B) gives them a good shot at winning in that order. Sanchez used the cubs because they weren't a winning team and clearly weren't going to be a winning team for several years and the difference in money wasn't much.
I'm of the opinion you make incremental improvements until you're at a position to where you're a legit team and then you go for it. I don't believe you make the big money play in the hope that it puts you as a legit team. Again, if they sign Lester I'm pretty ambivalent to it. I don't hate it and I don't love it. I'm of the opinion that it wont really make a huge impact in terms of wins/losses.
Well here's my take on this.
A. You sign said player because right now, the larger market teams, meaning the Yanks, Dodgers, Phillies, and Tigers are not all that interested, although, things can always change. Next year, or two years from now, that is very likely to change and we have seen already, the Cubs simply WILL NOT go the route other teams will as far as years, money, and no-trade clauses. Maybe they go one of the three or two, but their is always a catch by some other team that seems to doom the Cubs.
B. It is of the utmost importance to me to also send a message to your team that the FO indeed is behind you and believes that a couple of moves just might make the difference in preparation for the upcoming year. Competitors want a chance to win, and having E-Jax and Travis Wood taking the hill every fourth and fifth day spells doomsday all over again. I know if I were a player, I would be pissed. I don't know how long everyone thinks that Rizzo and Castro are going to wait around for things to happen.
You want incremental changes? Go and get a frontline pitcher and build off of that. Then in pursuit of pitching next year or the following year, you at least have two ponies in the stable and can get that all important third one via free agency or trade. If the Cubs were not thinking along the same lines, they wouldn't even be talking to Lester tomorrow..........or today.
