Absolutely not, If rosen is that good he can fight off Tua or whomever we draft then yeah.. How would you feel if we skipped on Tua he goes to the jets after darnold fizzles out and wins a superbowl.. NO it just doesn't make sense to me to take that risk, Rosen will get the starting gig in 2020 to start and it will be with a young talented newly rebuilt roster .. IF he goes and Throws 35 tds the next season he keeps his job simple as that, if he falters Its Tua time but He will start next season to buy tua a chance to get comfortable as an NFL QB.
You do realize if we draft Tua, Rosen plays well and he doesn't see the field because of it we can STILL get a kings ransom for Tua, SImilar to how the chargers the situation when they had Drew Brees and Phillip RIvers god they made the mistake in that one but if Bree's hadn't gotten injured they would have likely been able to trade him for multiple 1st rounders.
