i'd keep both return spec pieces. you could just use the SPs later on and pump up headfake and juke. no amount of SAs will let you get to 10 return spec.
you really don't need a whole lot more vision. once you have maxed special teamer and return man....thats a 60% vision bonus. that would have you returning kicks at 100 vision without putting any more into it. You could take it to 68 if you want, but seems a bit overkill going from 101 to 109 vision.
if it were me.... i'd take carry to 60 or 68, soft cap jumping (not sure why....just seems like a good idea) then pump the hell out of all your SAs.... first step, spin, quick cut, juke, headfake.....perfect.
once special teamer and return man are maxed and you have decent SAs, pump up quick feet, then slippery.
i'd also be training str/carry until carry goes below 10-11%, so probably 2-3 points up for it. then train stam.
after that you can specialize your guy....if you want him to be a pure special teamer, bring up tackling...if you want him to still be able to catch, catching/jumping
