Tampa actually went 11-5. But you're point is well noted. However it took them much longer to become a legitimate team than 4 years. NFC playoffs or not they were dubbed the "Yucks" forever.
I agree with rittenhouserobz the Houston offense can't really me much worse than it was in the last two seasons and if I recall correctly our offense early on in the 2003 season was ranked 10th overall in the NFL. So it showed some flashes last year which was a precursor of what is to come. I remember being very excited about that. They will improve it will just take time.
