And then there were eight (unsigned first-round picks).

After Detroit signed 23rd overall pick Riley Reiff this morning, the Steelers have followed suit, getting 24th pick David DeCastro signed, according to Ed Bouchette of the Pittsburgh Post-Gazette.

The guard from Stanford will get a four-year deal worth $7.814 million, per the slotted system that makes these deals so much easier to reach than they used to be.

The Steelers report to training camp in Latrobe, Pa., Wednesday, and with the DeCastro deal, the entire draft class has now been signed.

Now there are just 23 unsigned picks total, a number which will diminish rapidly in the next few days.
