Well, we could select the best longsnapper in the draft if we want a starter.There's a strong chance that no matter who we start at 13, he won't start in year 1.
A WR would likely get a lot of snaps so we can call him a starter at that spot.
Other than that, where do we have an automatic starter?
OL? Nope.
DL? Nope (I disagree that Miller or Hunter would put Ford on the bench.)
TE? Nope
Secondary? Nope
QB? Nope
If we insist on a year starter, we're limiting ourselves to WR, and I'm certain they don't want to do that.
