Alabama will be in some tight games with very slim margins. They’ve already been in one this year. Special Teams can give you an advantage if you have the right weapons. So it makes sense playing someone like Waddle.
The tough part is BYU doesn’t seem to have any special teams weapons (meaning in the return game) so get Milne out if there. He’s not making any game changing difference while out there on ST so go grab a backup that can yield the same results.
