First, I'd consider going max Height and min Weight. That's 6'6" and 195#. It helps to be tall in the Passing game.
Instead of Soft Hands add Workhorse. Even for Speed Receivers a lot of catches are Catch in Traffic types until Vet when you get elite Speed to really get open. Soft Hands is a negative for that. And you will need Conditioning.
Experiment with dropping Stamina to 1 and then slowly adding that 1 point back. 6 Stamina for 45 Conditioning isn't a great trade-off. 4 or 5 is probably a better spot. Move the Stam point into Confidence as that improves your catching ability. You can probably drop 1 point out of Awareness too. Medium to Deep passes give the WR more time to adjust, so you don't need 80+ Awareness. 70+ should be fine. Also, you don't need 9 Speed. 8 is fine. (with Egotist/Speedster) You're not a Superstar. 8 Speed gets you to 91 Sprinting whereas 9 Speed gets you to 99. If you get 91 Sprinting, you'll be plenty fast and the SP cost to get to 99 is insanely high for a non-S* and cripples your build to do other stuff.
In essence, Workhorse is like adding 1 point to Stam but you get the full benefit of that 1 point. ie 10 points in Conditioning. You're using Salary to buy an Attribute is the way to think about it.
Then you get Cap Boosters which in total add 15 skill points or equiv to 1.5 Attribute points.
So if you're 4 Stam with Workhorse and Cap Boosters, your final Conditioning skill should be 50+.
I made a Mock Build for you here:
http://glb2.warriorgeneral.com/game/player/130171Str: 1 Spd: 7 Agi: 8 Stam: 4 Awr: 7 Conf: 8
Conditioning of 44 can be boosted to 59. That's enough for a non-S* WR.
This build has 84 Sprinting. Think that's not enough? Well one of the top WR in HoF has 80 Sprinting and one has 88 and they are both S*.
Rec Hands: 74 Catch in Traffic: 56 Route Tech: 73 Route Elusive: 75 Route Aware: 72 Route Consistency: 75
Max all Receiving Skills, Max Conditioning with Cap Boosters, get 40+ Heart and then pound Sprinting and Quickness. (Not exactly, but you get the idea.)
Galithor would tell you to get Head Fake Gold, First Step Gold and Prime Time Silver as your SA's. (I believe.)
