Almost every team in every sport that made a "miraculous" turnaround from one year to another had the seeds in place the previous year. Look at the '86 to '88 Bills (I don't count '87 because the strike messed everything up)...they were coming off two consecutive 2-14 seasons and went 4-12 in '86, but they hired a new coach that year, had Kelly, Reed, Talley, Tasker, Hull, Smith etc. So you could see it was coming.
As a Mets fan I can cite the '83-'84 squad as an example as well. That '83 squad won only 68 games but you could see the talent bubbling up -- Straw, Darling, Backman, etc, with Gooden racing through the farm system... and in '84 they won over 90 games and were good for the next six years.
A few weeks ago I would have said there's nothing in the cupboards here to suggest that this team will make a turnaround within a year or two. I'm still not sure there is. But at the very least I can say this team is moving in the right direction. They've cut loose players who were tied to the last few years of futility -- Edwards, Lynch, etc -- and not only benched but deactivated first-rounders like Maybin and McCargo who clearly weren't getting it done at all. I really think that the improved play of the team over the last two weeks is a direct result of that message.
I know wins are the bottom line. But wins are a crutch too ("he just wins," etc), and they paper over deficiencies that otherwise would be corrected. I think we are better off right now at 0-7 than we were in any 7-9 year under Jauron.
