Newbie to posting and newbie to Crappie fishing.

Scenario: A buddy of mine and I fished a tournament in Baldwin County (Hubbards Landing) several weeks ago. We pre-fished on Friday and then the tournament on Saturday. Caught in the neighborhood of 80-90 fish in the two days. 80-90% of the fish were 8-9" . We spider rigged minnows and a few jigs. 1 big fish (#1.04) nothing else close to that fish. Most of the other fisherman catching the same thing we were catching. Fished on the Alabama River over Memorial day weekend for about 2 hours and caught 4 -14" and 5 or 6 ,11" fish and only a couple small fish. It was an awesome trip with some really good quality fish.
Last Friday Back in Baldwin County( Mifflin Lake) repeated the first trip. caught 40 -50 fish by 11:00 with 7 that would make the grease. 1 fish 13".

Question: Is there a really strong age class of 8-9" fish in the Delta or is there a stunting of fish due to so many crappie in these waters?


Or am I not fishing where the big ones are?
I hope that its a really good age class and that next year there will be a plethora of 9-11" fish but I sorta doubt it. Stomach contents were slim to none. Anyone else noticing this localized situation? Its almost like a bass pond that's over crowded. a few bass will get thru the choke point and turn into really nice fish but the majority of the fish are stunted and resemble a yearling bass although they may be 3- 4 yrs old.
