I wouldn't. Locating the ball is only an issue on deep passes, and I don't believe many WRs have a problem locating the ball. IMO, body control & timing are the key factors. Most WRs get to the spot, they just don't get their under enough control to make a play, or they mis-time their jump, or they get bumped off by a DB. But it's quite rare that I see a WR not able to locate a deep ball.
When I see Fitzgerald & Moss make these plays, they're usually jumping over someone that was just as good getting under the ball as them. The difference is they get there under control while their opponent is off balance and unable to make a strong attempt on the ball. In Fitzgerald's case, I think his strength helps as well. He doesn't get bumped off track and quite often uses his body to do just that to DBs.
Reed makes those plays with his anticipation and athletic ability. I don't believe he locates the ball better than anyone else. I believe his experience, knowledge & preparation get him to the ball quicker & more often. And then he has that same level of body control when it comes to getting to the ball under control so he can make a play.
IMO, minipulating a players ability to locate the ball is unecessary. I believe the effect you're looking for can be accomplished with a number of approach, jump & bump animations. Fitzgerald, Moss & others get to the spot under control and jump perfectly most of the time. Lesser WRs may stumble when gathering themselves to jump and not jump as high, jump late or jump off target as a result. Fitzgerald's strength can help provide space around him where a smaller WR may get bumped off target when approaching the ball.
There are a number of factors that go into making plays on deep balls. IMO, locating the ball is the least of them. But I wouldn't mind it being in the game if a non-invasive method was used.
