catch in traffic is most important for the slot reciever...(my team has horrible recievers but i'll explain later)
the rest of the ratings depend on the type of offense you use..
i would assume if you go deep a lot speed would be very important as well as acceleration..etc etc., one of the reasons i love this game is because balanced playcalling determines a lot in terms of the success your passing offense will have, NOT just ratings
i personally go for the biggest freaks with the most speed but hey i'm the raiders and i draft like al davis so what do i know
i use the speed philosophy and as it stands right now i'm using chaz schilens (got him up to an 81) todd watkins (got him up to an 86) and Johnnie Lee Higgens (got him up to an 86), javon walker has regressed to a 76 and is my 4th wr because i can't afford to cut him....
jamarcus is up to an 84 and i've won two straight super bowls in my first two years(wasn't easy trying to mantain as much as the RL team as possible
) and i'm just starting my 3rd year and i used claystone's 95rba sliders my first year and in the second year i used claystone's latest sliders....both years finished 12-4, i don't sim
...i love this game. because really how well your receivers do is pretty much entirely up to you.
