Experts say it takes three years to properly evaluate a draft class and the related undrafted free agent signings, but the veteran free agent signings can be evaluated sooner, often during the first season.
But we warm blooded fans are impatient and don’t want to wait for the games be played, we want instant gratification. Which is why God created pundits, who by the nature of what they do evaluate right away. They make the time between the end of the Super Bowl and the beginning of the next season bearable, feeding fan’s optimism or reinforcing their worst fears.
