5 surprising cuts from the 49ers' opening 53-man roster

49ers shocking roster cut No. 2: Safety Myles Hartsfield

Speaking of the defensive backfield, two of defensive coordinator Steve Wilks' hand-picked offseason additions didn't exactly jump off the page for the right reasons.

Wilks wanted former Atlanta Falcons nickel cornerback Isaiah Oliver, who had over $2.9 million in guaranteed money on his two-year free-agent deal signed earlier this offseason. Considering that Oliver was a massive liability in preseason games, though, the Niners probably wish they hadn't agreed to those terms.

The other player Wilks wanted to have, former Panthers safety Myles Hartsfield, didn't survive roster cuts.

Now, Hartsfield didn't carry any guaranteed money on his contract, so no damage there. But it's a bit concerning to see two of Wilks' primary offseason targets trending in the wrong direction.

And, in the case of Hartsfield, off the roster altogether.
