I don't think he's saying he'd bail on the team 98greenc5. As I read it he's asking if this would be a viable on going stragety. Could you do this year in and year out and be competitive at the highest levels.
I don't have much experience, but my gut says no. Without getting good draft picks, you aren't getting the trade bait you'd need to bring in top quality players, who didn't come from the free agent pool, and if the free agent pool has been anything like the two worlds I've been involved in, then there just aren't enough "great players" to make it worth it.
But again, I've only got one full season of experience, and just started with my second team, so take that opinion for what its worth.
