I think it's time I looked at special teams setups. I know kick holder and a long snapper are important. What else do you guys like for returners and the blockers/rushers/gunners?

Here is setherick's excellent primer on special teams:

Wow, I just did the overrides, most of those spots were blank. I'm excited for my next game!

Another question, what makes a good returner? I've noticed when you search your roster for cur/fut ratings for a returner, some of the results don't have good kick catching?

In my opinion, worth absolutely nothing, a good KR should have 60 kick catching, 100 speed, 40 acceleration, 50 break tackle, and 50 avoid fumble.

But as I said, that just my opinion worth absolutely nothing

Add in 70 ball carrying and I agree with you. Gotta follow your blocks.

Don't I want FB's and TE's blocking ahead of my returner? I'm not sure why their ratings are so low in those spots

Does anyone have anything about this?

The kickoff return team does not use real football logic for the positions. I TEs and FBs in those same positions.

So those ratings don't really matter, just as long as their specific attributes are well suited for the position? I am trying to follow Seth's guide.
