Agger was our best defender last season, Sakho was worst

Last season Brendan Rodgers utlilized 16 different line-ups on the back line.  I remember back in the day when Benitez used to change the line-up that often, he was ridiculed as a 'tinkerer'.  The truth is, he was ahead of his time and most successful managers started to do the same including Mourinho and Ferguson. Nowadays it's the status quo for clubs involved in multiple competitions, especially Europe (Sorry Man U).

 Rodgers, though, had a ton of injury issues to deal with last season.  Sakho, Enrique, Johnson, Toure, and Agger all had injury spells, some multiple.  Here are those line-ups along with their stats:

				M	GA	GAPM	CS
Johnson	Toure	Agger	Enrique	2	0	0.00	2
Johnson	Skrtel	Agger	Enrique	1	0	0.00	1
Johnson	Skrtel	Agger	Cissohko	2	0	0.00	2
Johnson	Skrtel	Sakho	Flanagan	3	2	0.67	1
Toure	Skrtel	Agger	Sakho	1	1	1.00	0
Flanagan	Skrtel	Toure	Cissohko	4	4	1.00	1
Johnson	Skrtel	Agger	Flanagan	5	5	1.00	2
Toure	Skrtel	Sakho		5	7	1.40	0
Flanagan	Skrtel	Agger	Johnson	2	3	1.50	1
Wisdom	Skrtel	Sakho	Enrique	1	2	2.00	0
Johnson	Skrtel	Agger	Flanagan	2	4	2.00	0
Johnson	Skrtel	Sakho	Cissohko	1	2	2.00	0
Johnson	Skrtel	Sakho	Agger	1	2	2.00	0
Johnson	Skrtel	Sakho	Flanagan	5	10	2.00	0
Johnson	Skrtel	Toure	Cissohko	2	5	2.50	0
Johnson	Skrtel	Toure	Flanagan	1	3	3.00	0

Those are sorted by goals allowed per match and if we break it down per player:

	ms	ga	gapm	cs	cs%
Agger	16	15	0.94	8	0.50
Cissohko	9	11	1.22	3	0.33
Johnson	27	36	1.33	9	0.33
Toure	15	20	1.33	3	0.20
Skrtel	36	50	1.39	8	0.22
Flanagan	22	31	1.41	5	0.23
Sakho	17	26	1.53	1	0.06

It's pretty clear our most valuable player on the back line is Agger.  It's not even close.  In fact, we only had 2 clean sheets without him.  What's disappointing is Sakho appears to be the biggest liability.  One clean sheet in 17 starts and the highest goal allowed per match average at 1.53.

I'm not sure what Rodgers plans on doing since it was pretty clear by the end of last season that Skrtel and Sakho were his first choice centre backs.  If they continue last year's form, that's not acceptable.  Agger is our best defensive back and I don't know what else proof the gaffer needs.  We will not win the league next year unless we shore up our defense, no matter what hard decisions need to be made.  I like Sakho, but if that means sitting him, so be it.
