even if that were the case, would still should not be offensive rookie of the year. create special teams rookie of the year if you want, but that's like saying if a defender scored 10 TDs they should get OROY votes. they aren't offensive players.
Except it's not like that because such a defender has an award he would win.
I guess you could create an award, but why?
You'd be creating an award for basically a 1-time use. There are few rookie special teamers who do so much that an annual award is warranted.
If a rookie WR set the record for single season PR and KR TDs, but only had modest WR stats, what should he win? By all accounts it was his special teams play that won him the award.
I don't see any point in creating awards for the sake of preserving some sense of appropriateness for a given position or positional group.
Any kicker who accomplished what I think it would take for consideration would be deserving of OROY, IMO.
