My whole issue with this trade is...there is no way we will be able to evaluate him in 1 year when it is time to make a decision on the 2020 QB. Our line and team are worse than AZ, so everyone will say...just give him time...he will be great when he has a good line in front of him...all lines we have heard for the last 7 yrs with Tannehill really.
I don't mind the trade for the player, just hated what we gave up, and still don't understand the plan. Rosen will be back in the exact same situation come 2020 that he was in now (playing backup to a top drafted QB). If he is ok being a backup then thats fine, but who knows.
