defensive guys on offense and offensive guys on defense?

I'm a ps3 player and I don't know how to do defensive guys on offense and offensive guys on defense, like I've heard that guys are putting there tall wr's at cb and safety to defense rocket catches but I don't know how to do that, and is it at all possible to put a wr at te ? maybe I'm truly missing something obvious but I could still use the help anyways guys, thanks....

what you do when playing press pause go to strategy depth chart and there u go. as far as subbing wr for te no u cant do that

I don't know why you would want to, it'd be almost impossible to run without a good blocking TE

nawwww! don't play like that bruh! WRs are not DBs and visa versa. but....i understand if someone moved a CB to FS/SS or even switch the safeties up. that actually happens.

this is very cheesy, but its only a game neway. the only thing is that fast WR's don't mean anything anymore, its all about the tall WR. the only good thing about fast WR's is screens, and good players recognize the formation and try to manually guard it

I've seen people put Adam Jones as a WR due to his 80 Catch and speed.
But he's released now and small :]

yea, kinda makes the game unrealistic in a way
