Again, in a salary cap era, I'd rather be a team that has a long-term plan and will be a major contender for many years as a result of said plan.
Going all out (disregarding sound cap management, throwing away picks, etc) for a one or two year shot at the expense of a long-term plan seems foolish to me.
As many teams have proven — most recently Denver — it seldom, if ever works, whereas teams like Seattle, Green Bay, NE, Pitt and even NYG (built with home-grown talent) have had more success than failures over the long term.
I realize that Romo is on or near the downside of his career, but IMO, if the plan of building an entire team with home-grown talent (which includes finding a QB) is properly addressed, I like our chances.
