Hate to interpose facts into a "legend of Big Mac the QB guru" thread, but here goes.
Scott Tolzien was a nobody, journeyman QB who was largely allowed to be Rodgers backup QB in 2013 because he played collegiately at Wisconsin.
After Rodgers got hurt mid-season in 2013, Tolzien, in his regular season debut, completed 24-of-39 attempts for 280 yards, one touchdown and two interceptions in a 27–13 loss to the Eagles. In his next start again the Giants, Tolzien went 24 of 34 and threw for 339 yards, but also threw 3 interceptions in a 27–13 loss. He started the next week against the Vikings but was so bad he was replaced and never started in GB again.
He was later allowed to walk and became the backup to Andrew Luck in Indy, where he signed a two-year contract worth just $3.50 million with $500,000 guaranteed (big $?).
In Indy, Tolzien started week 1 of 2017 against the Rams and threw for 128 passing yards with two interceptions returned for touchdowns, until being benched in favor of Jacoby Brisset in that game. That effectively ended the illustrious career of one Scott Tolzien.
As an aside, any guess which team Tolzien is a QB coach for now ... loyalty matters.
As for Brett Hundley, Big Mac enthusiastically praised the former UCLA QB when the Pack traded up to select him in the 5th round of the 2015 draft.
The QB whisperer then had 2 full seasons to mold Hundley as Rodgers' backup QB.
Thus, when Rodgers went down in game 6 of the 2017 season (with the Pack at 4-1 and in a 0-0 game) Big Mac defiantly declared the Packers had no need to bring in a QB from outside the organization (think Kap) ... "
I have three years invested in Brett Hundley, I have great confidence in Brett Hundley. I have two years invested in Joe Callahan. It’s a quarterback room that has structure.
I feel great about the room.” https://packerswire.usatoday.com/20...e-mccarthy-commits-to-hundley-callahan-at-qb/
Hundley rewarded Big Mac for all that confidence by going 3-7 and finishing with nine touchdowns and 12 interceptions.
Unbelievably, after years and years of stellar QB play, Hundley led the Packers to two shutout losses, at Lambeau.
When GB finally fired its (medically) incompetent GM in January of 2018, his successor quickly got rid of Hundley for a 6th round pick in a trade with Seattle.
Hundley then signed a one-year contract with the Cardinals worth $1.88 million in 2019.
GB got crappy play from, and nothing but a 6th round pick (a steal at that) in return for, Tolzien & Hundley. They both did next to nothing in the NFL.
But yeah, there is no doubt that Big Mac was their QB whisperer.
