I ain't falling for no banana in the tailpipe, man
but My initial impression was to guard against BahkT being gone. If they locked him, they still got highly rated Olineman. and regardless of what you think of last year, high on MY list of reasons why we fell short, started with the offensive line. We had a revolving door for a while, and nobody could fill in adequately.
So whether Spriggs was drafted for LT, RT, move to guard, guard against injury, play backup, whatever. As long as he does that well this year, I'm good. I'm sure they have future plans for him along the line and have more than one plan. Not having an Adequate pool of offensive lineman, IMO, sunk us further than any chubby RB, or WR's not getting separation, or no real ILB or any of the other reasons. I'm not disappointed they went and got someone they think helps.
