depends on what you want really.
you could go multiple ways with this,
for example, if you want a more rounded out WR you might want to consider getting str up to the 48 cap [breaking tackles] and/or confidence [helps nerf the "snowball effect" when your player has a drop]
you could go for a "YAC" type build, and move 1 EQ peice fully into agility and put sps into there as well [up to 80 with eq on], along with Quick Cut & some juke SA's, also strength would be recommended, and set your running style to super elusive/creative route running. best way to go if you are the #3 guy or lower on the DC imo. slippery/quick feet/yac attack would be ideal SA's if you go this route
or even speedster, and get your speed higher [110+ with eq] with points put into first step [10 natural, 11 with CE, and even 16 with a lvl 56 upgraded AEQ with FS].
ive also seen some who took jumping to the 60 cap to be more of a possession build/red zone threat. [str and confidence would be capped to 48 as well]
but yeah, just some ideas. builds are all about preference.
