I thought Whelan was known as a good holder. Why can't the back up centers just take the time to learn how to do the long snapping, I would think if I was trying to make it in the NFL as an offensive lineman, I would get as good at everything that might help me make the roster, and long snapping along with being able to play a position on the line on offense would certainly cross my mind as something that the team might consider valuable. It could give them an extra roster sopt at another position possibly. I remember Mark Chmura used to do the FG and punt snapping when he was his first couple years in the league and that may have been what kept him around, cause he sure wasn't the greatest TE when he got to GB. I would think those guys agents would tell them to learn to do the long snapping if they can. I don't know, maybe they have tried and they just aren't good enough at it.
