There is nothing wrong with waiting for your shot, as you learn from the sidelines, as Rodgers, Brady, Jackson, or Mahomes did.
Waiting for the line to learn to work as one unit, and show some consistency (Especially with probably 2 Rookies starting) is not a bad thing to have a Vet like Fitz back there early.
On the other hand, If Tua comes out, looking heads and shoulders better then everyone else...the coaching staff is going to have a very hard time keeping him from the Field.
Rodgers sat behind a hall of fame qb at the end of his career, mahomes sat behind alex smith on a playoff caliber team, brady was a 6th round pick who probably wouldnt have seen the field if bledsoe didnt get hit in the chest...lamar jackson entering the draft there was talk about him switching positions questioning his ability to play qb and flacco was being paid a ton of money and was their guy for 10 years and they were always "in the hunt" moreso for their defense than offense but still...
while i understand what youre saying these are all different situations from where were at...were a team who has a 37 year old journeyman qb, who i like btw dont get me wrong, and have been mired in mediocrity for 20 years, we have a young team in an admitted rebuild, wouldnt you want the centerpiece of said rebuild to build chemistry and get some experience?
in all honesty tho if hes deemed not good to go im actually ok with it, im really just giving my opinion on the situation were in at this point but ive waited long enough i can definitely ride out another season if i have to but i was reading something a month or so ago where they had a couple gms talking about the sitting and learning and they said they used to believe that method was sound but theyve changed their mind after seeing players make immediate impacts even if they have growing pains and struggles early, you basically learn nothing holding a clipboard, you learn by playing...
in tuas case his best attributes is his pocket presence and ability to read defenses, ive seen those things referred to as elite in some places...so i think it all depends on how quick he acclimates to that south florida weather, his health/strength/conditioning and his ability to grasp the playbook in a limited/shortened/no preseason games irregular offseason...
like i said tho, i think fitz starts the season but it wont be long before tuas under center...we know fitz can be careless and if hes not flawless there will be daily pressure from fans, the media and front office people (ross?) about tuas debut...we will see him at some point this year, hes already the face of the franchise
