The first part not really a bold statement. Since NE last won a Super Bowl, only 5 franchises have hoisted the Lombardi...
The second part is interesting. Would I love for them to go out and get a Larry Fitzgerald and Adrian Peterson to help this team? Not at the expense of developing the depth that is needed throughout an NFL season. Besides, people used to say that about the defense, but what happened? The have rebuilt on the fly by phasing older players out and bringing in younger ones. They literally did it position by position. They would draft secondary players one year, LB's the next, and so on. Look at it now, even with all of the injuries, a pretty formidable group.
On offense, they started by drafting Solder three years ago, the tight ends, then the running backs. This past year they added three rookie wr's. Is the personnel getting worse or is it getting younger, which will then trend up in the future? I would expect them to add a veteran wr this offseason, depth on the line, and a tight end. This is the second youngest team in the NFL which lost six former pro bowlers to season ending injuries, that had to rebuild its offense after the draft due to the tight end situation, and they were a win away from the Super Bowl.
