MarQueis Grey may be listed on the roster as "SAK", as he seemingly fits the profile of a Swiss army knife - the same term Jim Harbaugh used to describe Delanie Walker.
Gray is a true athlete, and the 49ers finally have an offensive coach who is innovative enough to make use of a mutli talented threat. Gray will be able to show case his talents, but tight end is probably where he can be best utilized. The 49ers though, like all their tight ends to be sound blockers and that is where Gray will have to prove his worth.
