At first it seems like a no-brainer to take it, but on second thoughts...
General knowledge says to start a rookie elf team with many linemen and only few positions, to allow reasonable ff and rr in the starting roster. Consequently, these linemen pick up the ball and quick pass it to someone else (your thrower, if available), to gain SPPs more quickly.
You see the pattern? Even IF there is a thrower around, he will NOT BE THE ONE to pick up the ball. If anything, he should get catch, as he will always be the target of those lineman passes (controversial thesis, ain't it?).

So, why give him sure hands? To counter strip ball? Usually, he will be far enough in his own backfield to be out of blitzing range and next turn he darts forward, hurling the ball to some receiver.
So, I'd suggest taking sure hands only as 3rd or 4th skill, when the linemen have their skills. Earlier, of course, when building that defensive thrower.
Logic reasoning or a dumb mind's foolishness?
