So if it only works under circumstances of consistently drafting well and that isn't happening, is it a good strategy? Or is it a better strategy to manage things a little tighter to create some roster flexibility?
Every true contender either drafted their QB and has them on a rookie or team-friendly (flexible) deal or, like Detroit, trading for an undervalued QB and built with strong drafts. Look at the true contenders in the league:
SF
Baltimore
Buffalo
Miami (pre-injuries)
KC (though fading bc of poor drafts)
Philly
Dallas
Houston and GB may not be “contenders” but they’re so young bc of solid drafting and with young QBs that they’re getting close.
See the trend? Nothing to do with how they manage the cap.
