3 first-round NFL Draft mistakes that continue to haunt 49ers

The 49ers have had some hits in Round 1 of the NFL Draft, but they've also had some serious gaffes that continue to haunt them to this day.

Back in 2017, the San Francisco 49ers were one of nine teams picking atop the NFL Draft that could have simply stood pat and grabbed Texas Tech quarterback Patrick Mahomes.

Instead, the Kansas City Chiefs jumped up to No. 10 overall, grabbed Mahomes and turned him into a two-time MVP and easily the best quarterback going in the NFL right now.

Oh, and he's also beaten the Niners twice in the Super Bowl, two of the three Lombardi Trophies he's helped KC hoist.

Amid the first year of what was going to be a lengthy rebuild under general manager John Lynch and head coach Kyle Shanahan, San Francisco's plan was well-documented. The team wasn't going to pluck a quarterback right away at No. 2 overall. No, the plan was to build through the trenches, ink then-Washington Redskins quarterback Kirk Cousins in free agency in 2018, and that would be that.

The 49ers' top pick that year? Now-New York Jets defensive end Solomon Thomas, who never came close to meeting expectations.

That whiff was a massive one for the Niners, who have felt the sting arguably a little more than the other eight teams who ultimately passed on Mahomes if for no other reason than San Francisco has tasted bitter Super Bowl defeat at his hands twice now.

But it's not the only first-round gaffe in the Lynch and Shanahan era.

Let's take a look at three more.
