I see people are upset with this post. I will try to ask honestly: "Seriously, what do you think the trajectory is for physical growth and improvement?"
See in a sport like say baseball you peak at or before the age of 25... You stay at or close to that level for a handful of years and then you start to decline... The decline accelerates as you pass the age of 30... (It is not so very different in football.) Bill James studied baseball statistics and looked at the age of the players and noticed a correlation between career numbers and ages at or less than 25 years old. Tens of thousands of players over a 100 year span... The sample size is enormous and the data is undeniable.
Without looking deep into this (I enjoy a good debate, but I am also lazy) There has to be studies like this for football as well.
Now it has happened that players in baseball got better later in life... It was not physical for these guys... It was mental
So if you argued that Tua's mental maturity could improve slightly... I would listen to that argument. (It might not be a great argument, but I would listen)
But if we are talking about physical ability or Physical performance. There comes a point in football like baseball where physically players peak and then start to decline.
Tua has been in the league for 5 years now. I know he was not the starter the whole time and we all know he missed time due to injuries. But Physically he is in his prime... He should be at or very close to his peak physically. He is never going to be able to move his feet faster... or rotate his hips faster... His reflexes and reactions times will not get any better than they are now.
So... How much more improvement can we expect in terms of getting the football out faster? or making the reads faster.
It takes so long for the eyeball to process what is in front of it. Then it takes time to send the message to the brain. Then it takes time to process this and to decide what to do. Tua's brain is young... He is in his prime... As he ages from here his processing time can only go down.
So where is the improvement going to come from with Tua? Judgement? Accuracy? See maybe he makes miniscule improvements in this category... But noticable jumps ahead are very unlikely. And be fair....(For the Tua fans here.) How often have you praised his accuracy or his maturity? I am betting a lot. So it is not logical for people to now argue that Tua was lacking in these areas and thus likely for massive improvement. He is already atop of the league in accuracy and maturity.
From what I have seen here with the Tua fans, is nothing but praise about how he has improved etc... I have not seen people posting that his footwork sucks and needs massive improvement. I have not seen posts where people break down his throwing motion and state that he needs massive improvement. So you all mostly agree the footwork, the arm angle, the release point, the hip rotation have been great. So if Tua has all of this room for improvement and growth. Where is it going to come from? In the areas I just made an example of... The ones where the bulk of the posters here do not think Tua needs major improvement? No massive improvement is unlikely (Because he is already sound in these areas.)
So any improvement from Tua is going to be miniscule. Which is why I said that maybe we have seen who Tua is... And that I do not feel it is likely he will make any noticable improvements.
I know this was wordy... But please enlighten me how we should expect these better numbers from Tua.
Remember that Brady had rings before he was 26... So does Mahomes. Marino and Burrow went to the superbowl before they were 26...I know Matt Stafford did not get to the Superbowl until he was in his 30's But he needed to get on a team with elite weapons around him to get his ring. Tua has the elite weapons...
The more the league changes and the more the QB's are paid the more important it is to win with the QB on his rookie contract.
