WRs go for balls that are thrown to them. There's never a, "do I want to actually try and catch this ball that the QB decided to throw to me?" check.
I don't do the programming for GLB, but I can promise you that.
Catching is the most important attribute considered in:
1. Whether you are thrown to
2. Whether or not you catch the ball
Jumping, vision, speed, agility, energy, morale, SAs, etc. <--These are likely all factors in the above as well.
The only thing that you can gamble on in this equation is whether or not attributes like jumping, vision, speed, agility, energy, morale and SAs (etc.) affect your ability to
catch differently than your
likelihood of being thrown to.
IE: Pretend every 1 point of jumping you have is equal to 1 tally of "persuasion" to the QB, an indicator of your skill if you will.
Furthermore, if that 1 point of jumping then equals 1 tally of "ability" in gameplay, instead of being an indicator it's your actual chance to come down with the ball...
The same with catching: Every 1 point of catching is 1 point of persuasion and 1 point of ability.
BUT, what if that ratio for jumping were not 1:1? What if when the QB considered your jumping attribute when determining to throw to you it meant .9, yet your ability remained at the flat 1 increase? -And catching was still 1 to persuasion and 1 to ability?
You'd see guys with
50 catching
40 jumping
40 vision
dropping less passes than guys with
70 catching
25 jumping
25 vision
(only a 10 point difference, but significantly more catching so he'd likely get the looks)
Maybe I'm incorrect in my interpretation.
Something to think about maybe?
Edit: and to answer the OP, I'd say no, but they're definitely both important.
