You have to ask "is this team significantly better than the 1-15 team?". And my answer is: only slightly. 80% new roster with little veteran leadership and it's not that much better. And does that make sparano and Ireland failures?
Special teams have gotten better but are still weak except for the punter and kicker. We still have no returner.
Defensively there are still gaps, but that pales in comparison to the offense where we need additional depth and may need to replace one or two guys (again).
QB is a pressing need. Ricky isn't getting any younger and Ronnie is in the last year of his contract, with no real depth behind them, so RB is a need.
Tight end needs to be addressed and we still need at least one more receiver. How the heck are they going to address all those needs this offseason?
Ugh. Like I said, the problems run deep.
