The bye week for a 1-6 team is a good time to start looking at the upcoming quarterback class. The 49ers are currently slated for the second-overall pick in the NFL draft and it looks like they’re going to stay in that neighborhood barring a drastic and unlikely turnaround.

That means there’s a good chance San Francisco will have a number of signal callers to choose from when its their time to pick April 28. All three quarterbacks on San Francisco’s roster could be free agents in the spring.

The biggest questions about the quarterbacks in this year’s class – we’re 183 days from Round 1 – is which draft eligible players will declare and which are worthy of getting pick atop the draft?

Let’s take an introductory look at some names.

DeShone Kizer, Notre Dame (junior)

Kizer began the year as one of the top quarterback prospects in the country. But a disappointing season led to speculation about potentially returning to South Bend for his senior season to hone his craft. Notre Dame is 2-5 after playing in the Fiesta Bowl last year while Kizer’s statistics have taken a slight dip overall, including completion percentage.

Kizer has great size (6-foot-4, 230) and athleticism. But he’s thrown interceptions in six straight games and has struggled with his consistency. At his best, he’s arguably the most well-rounded and pro-ready quarterback in the class. But inaccuracy issues could leave teams questioning if he’s worth getting picked early in the first round next spring.

Deshaun Watson, Clemson (junior)

Watson (6-foot-3, 215) is the most athletic quarterback in this class after taking the country by storm last season when he led Clemson to the College Football Playoff. But there are questions about his accuracy and ability to read defenses, which could give teams pause picking at the top of the draft.

For the 49ers, they might not be willing to go down that road with an athletic quarterback given everything that’s happened with Colin Kaepernick over the last three seasons. San Francisco might be more inclined to find a traditional quarterback they trust to win with his arm rather than athleticism.

Another note: Watson’s numbers have declined across the board in each of his three seasons. In eight games in 2014, his passer rating was 188.6 while he averaged 10.7 yards per attempt. His ratings in 2015 and 2016: 156.3 and 146.4, respectively. Yards per attempt: 8.4 and 7.6. And he’s only averaging 3.9 yards per carry with one touchdown after averaging 5.3 with 12 scores last season.

Brad Kaaya, Miami (junior)

Kaaya (6-foot-4, 215) is the most prototypical pocket quarterback among the top three prospects in this class. He doesn’t have much athleticism or very quick feet, but he’s known for being functional in the pocket and good at throwing accurately deep down field. He had the added benefit of playing in a pro-style offense during his first two seasons with the Hurricanes.

Unlike Kizer and Watson, Kaaya’s statistics have improved during his junior season. He’s completing 61.7 percent of his passes, putting him over 60 percent of his college career without a spread system that relies heavily on pre-determined throws.

Miami’s currently in a three-game losing streak before taking on Notre Dame Saturday – which should be a must-watch for 49ers fans/draft nerds – due largely to struggles on offense. Kaaya’s offensive line hasn’t been particularly good at any point in his college career, the running game isn’t providing enough and Kaaya lacks talented pass catchers on the outside.

Chad Kelly, Mississippi (senior)

Kelly (6-foot-2, 215) has undeniable talent. He’s Jim Kelly’s nephew and makes some ‘wow’ plays with his arm. But there are a number of questions about Kelly off the field, including – but not limited to – getting into a fight at a recent high school game.

He was also kicked off the Clemson team in 2014 for a myriad of issues, including butting heads with coaches. But he’s got a ton of physical talent highlighted by his elite arm strength.

The question becomes whether or not a team is willing to take a chance on making him a franchise quarterback given his brash personality that’s ruffled feathers along the way. The comparisons to Jay Cutler seem valid.

Mason Rudolph, Oklahoma State (junior)

Rudolph (6-foot-5, 245) is among the second tier of prospects that might find himself in the second or third rounds. He’s another classic pocket passer with a big arm. But knocks on Rudolph are his anticipation and ability to throw to receivers before they break open.

Rudolph had a strange wrinkle during his first season as the starter in 2015: He split red-zone snaps with his back-up quarterback J.W. Walsh, who was the better runner. Rudolph is getting 100 percent of the red-zone snaps now, leading to an impressive 14-2 touchdown-to-interception ratio.

Rudolph will be an interesting player to watch as the season goes on. He’s one of the few quarterbacks in this class riding an upward trajectory.

Mitch Trubisky, North Carolina (junior)

Trubisky (6-foot-3, 220) came into the season as a sleeper. He’s starting for the first time in 2016 after completing 40 of 47 snaps passes (85 percent) as a sophomore last year. This season, his efficiency isn’t quite as ridiculous. He’s down to a 71.2 percent completion rate with 18 touchdowns and two interceptions, which are awfully impressive totals.

Trubisky benefits from a screen-heavy offense and talented receivers. The sample size is admittedly small, but if he’s able to continue putting up crazy efficiency numbers, he might find himself in first-round discussion come draft time.

Trubisky could be a candidate for an early second-round pick if the 49ers look to address other needs – edge rusher or receiver – with their first-round pick.

Luke Falk, Washington State (junior)

Falk (6-foot-4, 216) plays in a Mike Leach spread offense that hasn’t produced NFL-quality prospects in the past. But his gaudy stat totals are hard to ignore in a conference that features pretty good defenses.

Falk is another player completing well over 70 percent of his throws this season – although many are a product of the spread system. He threw 38 touchdowns to just eight interceptions as a sophomore in 2015. Falk looks like a mid-round prospect.
