When was the last time the patriots drafted a decent corner? I think Flowers deal wasn't bad at all. If we're relying on the draft or cuts, there will be a serious problem in the secondary. Seasons aren't won on march 13th, however, no matter how much Kool-aid you drink (and you seem to have had a lot), you need talent on the roster.
As of right now, Arrington/Ryan/Dennard/Butler is the unit they'll be trotting out there. Can that change? Absolutely! But as the options dry up, I lose faith, because they've done it before, and it's the "patriot way"
