DeadmaN

I was watching the game last week with my soon to be father-in-law when subject of the bucks game came up and he posed an interesting idea

Mind you, I didn't get the chance to see this game cause I was working so I'm not sure how it went down exactly but he pointed out that on that last drive by the bucks they were in a close a yardage position with us backed up against the goal line

He said that Jason David was out matched on a jump ball?
He then asked if there are any league rules that stopped an offensive player from being subbed as a defensive player

I told him I wasn't sure but I couldn’t see that it was against the rules I have seen the pat's use Randy Moss as a CB and I have seen them use Mike Vrable as a tight-end but again I wasn't sure

So he asked why we didn't put Colston who is 6'-4" and had grate hands or copper who is 6'-2" in the game instead of David who is 5'-8"

Anyone have any incite?
