Fast growing crappie rarely live beyond 5 years. Probably due to angling, but even stunted crappie top out at 8 to 10 years old. The faster a fish grows the shorter it's life. If it's 14 inches, I always tell folks to eat it. It probably doesn't have a year left in it anyway. There are the odd exceptions to this observation and they will reach 15+ inches. Never caught one on rod and reel in MO, but I have caught them electrofishing. I've caught 3 of them in 26 years. Two of them died from the stress.
