Does height play a role in the game? Like say I have a short wr under 5'11, would it be bad to send him down field and throw him jump ***** or does the game not use height as a factor?

I'm dying for it too .. I keep trying to get 6 footers as WRs and CBs .. lol

And if it does matter, PLEASE provide more 6'3 + players!! Lol

Yes, but only in like one place. See reply in this thread: https://mfn19.myfootballnow.com/community/thread/1/548?page=1#2950
