So because full rebuilds have gone bad before, we should never go for a full rebuild?
You should always be willing to gamble that you can fix a bad situation. Otherwise, you'd always be stuck with bad situations.
No, full rebuilds should be done very rarely, stability is how you build a franchise and attract good FA.....when you pick a coach you should give him 5 yrs to win a SB, 3 yrs to show improvement and to reach playoffs.....
