Top 5
Tua - just an incredible thrower of the football. Accurate, quick as a cat throwing, guts of a burglar. 3rd and 15? Big deal - it seemed like a 60% chance of conversion. He revived a tradition of high-end Alabama QBs.
Bryce - elusive (other than Daniels, the most elusive QB I can remember), smart and cool, great student of the position. (Played in a "meaningless", non-playoff, bowl game in his last year. Had a great game and continued a great example of Alabama players playing for their team when many don't for fear of injury or "more work". Especially a high draft pick like Bryce.) Won the Heisman trophy. Was the number 1 pick in the NFL draft.
Namath - forget stats - different game. Also, Shea Stadium. Few dump offs to RBs or short game of any kind to enhance comp %. Everything was downfield. IMO, Bryce would have had a 35-40 comp % with all of the downfield passing. Was a great athlete and smart and a great guy. He was the number 1 draft pick and more physically gifted than Bryce until injured. Became a transcendent 60s sports personality. More so than Bo Jackson but in a different way.
Stabler - same as Namath and all pre-80s QBs. Led Alabama to an undefeated season in 1966. Also, a great athlete and smart. Very accurate for his day. Great deep ball.
Mac - accurate and smart. Led Alabama to a historically great offensive season and NC in 2020.
Other great QBs:
Dixie Howell - along with Hutson, is credited by some as creating the first pass patterns in football history. Led Alabama to a NC in 1934, going 10-0 and easily handling undefeated Stanford in the Rose Bowl. Coach Bryant was the "other end" that year; Riley Smith was also on that team. In college football HOF.
Harry Gilmer - led Alabama to a 1945 season Rose Bowl victory (worse than the 34-14 score indicated in the boat-race over USC who was previously 9-0 in Rose Bowls. (That was the last "open" Rose Bowl as they wanted to keep the riff-raff out and include only moral stalwarts like PSU, MSU, Mich, OSU, Ill, NW, et al.)), along with upright hosts like USC, Cal, Wash). Alabama finished 10-0 and 2nd in AP to Army. Was a national phenom, making the jump pass famous. In college football HOF. Twice finished 5th in Heisman voting at a time when the South was often overlooked.1st pick of the 1948 NFL draft.
Steve Sloan - one of the more underrated players in Alabama's history. Took over for Namath when injured in 64 and led the team in the 2nd half of the season to a NC. Led Alabama to the NC in 65 with a thrilling upset win over Neb in the Orange Bowl. Threw for 296 yards, an anomaly for the day. A bowl record for Alabama for decades, IIRC.
AJ McCarron - led Alabama to 2 NCs and a 36-4 record in his 3 starting years. Was a good passer who finished 2nd in Heisman his Sr year. Held most of Alabama's passing records at the time he left.
Pooley Hubert, Riley Smith - mostly leaders and runners, but both led Alabama to NCs and both are in the college football HOF. Smith was the 2nd player taken in the first NFL draft in 1936.
Great stories:
Pat Trammell - was a great leader in a different way than Jay Barker. Mean and tough as nails - the personification of Coach Bryant's early teams. Led Alabama to Coach Bryant's first NC.
Jay Barker - few skills except leadership. Though not a very good or great college passer, he developed into a good college passer by his Sr year. Led Alabama to the 1992 NC.
Blake Sims - shockingly to fans, became Bama QB. His unselfish/team-first attitude and surprising skills made his year one of the most fun in Alabama history. Was a 2nd team All-SEC QB. In my years of following Alabama football (from Bryant forward), Blake along with Javier Arenas, for different reasons, are my 2 favorite players.
Jalen Hurts - Came to Alabama to be developed as a passer but was forced into action earlier (true Fr) than was good for his career. Played well but was surpassed by Tua (probably one of the more difficult decisions of CNS's career because Jalen is Saban's son in spirit). Handled the situation as well as anyone could. Ironically, but not surprisingly, he developed as a passer (begrudging kudos to Dan Enos) as he sat on the bench. In an amazing twist of fate, came off the bench in relief of Tua to win the 2018 SECC game.
Honorable mention:
Richard Todd - a great athlete, who may have been the best NFL passer to ever spend his entire college career in the wishbone. Alabama lost 3 games in the 3 years he started at Alabama, though he shared QB with Gary Rutledge in 73, was injured parts of 74 and 75. QB'ed Alabama's first bowl victory in 9 years in the 1975 season Sugar Bowl win over PSU. Was a first round pick of the Jets in the 1976 draft. Beginning in '77, started for 7 years with the Jets with mixed results (made playoffs 2 years, including reaching the AFC champ game in '82). Then started a year with the Saints.
Jeff Rutledge - led Alabama to a NC in 1978
Steadman Shealy - led Alabama to a NC in 1979. (The man Coach Bryant wanted to speak with about spiritual matters late in his life.)
Walter Lewis - spanned the Bryant to Perkins transition
Gary Hollingsworth - won first post-Bryant SEC title in 1989.
Special mention:
Bart Starr - primarily because of injury only started for one year at Alabama, but he won an SEC title. He went on to QB the most championships in NFL history until Tom Brady, winning 5 in 7 seasons, including the first 2 Super Bowls and the "Ice Bowl". He was a wonderful person and great representative of the University and state.
[Andrew Zow, Tyler Watts, Brodie Croyle] - pity they played on such mediocre teams. Shaun Alexander, Zow and Watts led Alabama to a surprise SEC title in 1999. With Croyle, Watts helped break UT's streak against Alabama in 2002. Watts ended up helping Alabama to two 10 win seasons during a dark time. Croyle helped with a 10 win season in the aforementioned 2002 season and led Alabama to another 10 win season in 2005. (These probably shouldn't be mentioned but can't help but thank them for coming to help in a dark day. If they had come at another time, their careers would have been very different.)
[JPW, GM] - good, not great QBs but JPW started the renaissance with his undefeated 2008 regular season, then GM had a great performance in the watershed SECC game vs UF as he QB'ed CNS's first NC at Alabama in 2009.
Jake Coker - tough leader, made several big plays in the 2nd half of a NC season, including the NC game, where he threw for over 300 yards - Alabama needed them all.
