49ers rookie No. 2: Cornerback Tariq Castro-Fields

The 49ers spent considerable effort reinforcing their cornerback room this offseason. And while grabbing former Kansas City Chiefs defensive back Charvarius Ward headlined the movement, the Niners also used two NFL Draft picks on corners, too, Samuel Womack in Round 5 and Tariq Castro-Fields in Round 6.

Castro-Fields, the former Penn State defensive back, has some likable attributes, including his 6-foot and 197-pound frame and coming from a high-profile collegiate program.

However, his chances of making San Francisco’s 53-man roster might simply be subjected to the numbers game. While Womack has a direct path to assume starting nickel duties, Castro-Fields is almost exclusively a boundary cornerback, and the 49ers have plenty of better options there right now.

In addition to Ward, the Niners can count upon Emmanuel Moseley and even Jason Verrett, provided the latter is healthy, while depth corners like Dontae Johnson and Ambry Thomas are assuredly higher than Castro-Fields on the depth chart.

If San Francisco ends up keeping six cornerbacks into the regular season, the rookie simply might not have a chance to secure one of those final depth spots unless he absolutely has an eye-popping training camp and preseason.
