Large Market Teams Do Not Conduct Fire Sales

Look at this quote from a Cubs blog (Obstructed View):

"It's too bad the Cubs don't have a couple more Garza's they could trade to add some elite talent to their farm system."

If the Cubs had three Garzas, they would not be rebuilding. As a big market team that finished the previous year with a near .500 record (+5 wins for each Garza), and quite a bit of financial flexibility, they would have gone all in. They probably would have signed Prince Fielder, C. J. Wilson (or Yu Darvish) and a right fielder. They would have made trades to improve the current club, such as emptying the farm to get Chase Headley from the Padres. They also would not have made trades that hurt the club this year with the intention of improving it in the future, i.e., they would not have traded Marshall and Cashner for prospects. Most importantly they would not have traded Garza I, Garza II and Garza III.
