yac attack is terrible imo unless you're a possession wr. you have what looks like a speedster build, so when you catch the ball past 10 yards yac attack won't trigger at all. You have quick feet at 15, but only 1 of the elusive SAs. I don't know it just doesn't seem to mesh to me somehow.
If you're going for short routes and trying to break tackles try upping these: Spin: 0 Juke: 0
Set your route running to creative as well as running style to elusive to take advantage of those SAs. Up slippery as well as that increases the chance to trigger your SAs. You might also consider shifting points into AGI.
I dunno I don't have that type of receiver. I have a big play guy.
The problem is that if you don't break a tackle, you're not going to amass a lot of yardage and your stats will be average #2 level at best. Try talking with your OC too and seeing what would work best.
