No doubt any QB taking those hit is not a good thing. However it was 1 game, we go from 1 extreme to the other and it becomes almost a joke. Romo took some shots in the Houston game, even when he got the passes off yet no talk of retirement after the game. Why Dallas won. After any loss I know coming here will be loaded with the extreme.
Personally, I'm of the opinion that a team should always be drafting and/or developing a QB. It's a good use of resources IMO. However, I do understand your point about over reaction. I just don't see this situation as that. I think the reality of the situation is that Romo is a player, who over time, is going to see diminishing physical capabilities. Because he is a player who, IMO, relies on the ability to do certain things physically, it's going to impact his game. I think it would be wise for the Cowboys to start looking at taking a good QB if the opportunity presents itself.
To be clear, it doesn't have to be a reach. I don't think they should trade up to get a Mariota and sacrifice the rest of the draft. I don't think that's what should happen but, if the opportunity is there to draft a good talent, then I think they should do that.
