My colts defense

Could someone help me with my colts D as far as what is a good Defense for them.I know their D is not the best but I'm trying to utilize their speed for a positive D.I'm getting ran on at will,getting passed on at will,everything my opponnet does works.Their not built for blitzing because they play more zone than anything.Slow corners, LB awarness is not good besides Gary Brackett but he is to short 5"8 .I'm running a 4-3 normal,4-3 under,and nickel.So should I call more zone or more man and which person should I control.I was using Bob sanders but since he has good awarness I let him do his thang so I put in Condren for Betha at free safety because of his speed and his 96 jump.Any advice would help guys or any good man blitzes or zone blitzes but most of all who should I control.Please Help

I almost always go with man on CG. As for some plays. I would use 46 Normal, their are a ton of ways to get your ends to come free off the edge. With Freeney and Mathis this should give you a real good pass rush.

They are also fast enough (your ends) that the colts run a really good all coverage D.

So here are two plays I would use.

46 Normal Cover 1 (Pass Rush Version)
Shift Line left
Crash Line Up
Reblitz LDE and LOLB (as they appear on the screen, so really the RDE and ROLB).
RDE in QB Contain
BNR coverage.

46 Normal Cover 1 (Coverage Version)
Shift LBs Right
DEs in purple Zones
WDT in QB Spy
Stack the MLB over the SDT
BNR

dey work real well, thx
