Do you select a kick returner based on speed or overall kick/punt return rating?
There is a difference. The returner that is the default no. 1 on the depth chart isn't necessarily a team's fastest guy. It takes the three A's to be a great returner in the NFL - awareness, agility and acceleration. But in Madden it seems it's more about flat out speed.
I actually prefer to use a mid 90's speed w/ a decent overall return rating. It seems like the guys that have high 90's speed are tougher to control and you often catch them over-running their blockers, especially on shorter kicks which you see a lot online. With my Dolphins I use Chris Chambers for return duties and can break one all the way back every couple games.
Put your fastest guys in with speed and acceleration before overall rating for returns.
