If Tua is healthy, he will play this season...too much talent, he will win over that team easily, and he will put on a show at practice. It will be too hard to keep him off the field unless the o-line is a disaster.
I'm not so sure. Part of the equation as to when he plays is also getting a brand new group of O-linemen (Jackson, Hunt, Kindley from the Draft - Karras, Flowers - free agents - Davis, Deiter and another "Joe Schmo" from last season) to come together and gel as a unit with a new O-line coach in a new Offensive system and this is more difficult and probably delayed with the Covid-19 virus social isolation.
I may be totally wrong, but I still think that we are rolling with Fitz in 2020 and "the Beard" continues to pull the team together and he's so experienced that he can take the hits while the O-line hopefully comes together. Tua's job this year is to learn to be a professional from Fitz, learn how to read NFL Defenses, learn how Fitz inspires teammates through his tough gritty play, learn how to win the respect of all teammates, learn how to take a loss and handle the media like a true pro, learn, learn, learn while his body recovers 100%... Furthermore, I have zero problem in playing Rosen, if Fitz gets injured or craps the bed. Josh is the Dolphins low cost insurance.
Besides, Aaron Rodgers waited 3 years on the bench behind Favre. Tony Romo waited 2 years with a clipboard before he got his shot. Tom Brady, Drew Brees and Pat Mahomes all spent a year on the bench waiting, watching and learning before getting their respective opportunities to start. I believe in Tua, but we don't have to rush. Patience, in this case, is a virtue.
