The little FACT that Smith is going to be in a whole new offense. One that he has never been in before. Under a coach he has never played for before. You don't know how he's going to do under a new coach and a new offense.
The Fact that we don't no if Albert is going to stay around after this year. Sure you could say we have a LT we don't need one but again the Packers could have said we don't need a QB and not drafted Rodgers. How did that work out. By the way we have the gm who was very involved in that. You can't just look at the here and now you have to be able to look ahead.
You also never answered if it's so stupid to pass on a QB when you need one and take a OT then why did the Rams do it and win the superbowl soon after? It's been done before it COULD happen again. Why just assume it won't
As for your question I think there are lots of reasons that he may have never done that. A good part falls on Alex Smith. But like I have said over and over you also have to look at coaching his first few years. I again ask you to show me 1 qb that played well under his first couple of head coaches. But again it really doesn't matter since he's going to be in a NEW offense maybe this offense will fit him better and he can put up those numbers. Maybe it won't but there's no reason at all to think it's impossible. Alex Smith has never been great in the NFL. Hes never been a superstar but he also hasn't be garbage. He's shown some signs that he can be a very good QB under the right conditions. Before you start talking about how stupid it was what's so wrong with seeing how he does in this offense. Even the GREATS in the game have struggled when the offense wasn't right for them.
Randy Moss: did great with the Vikings went to oakland people thought he was done he went to New England and BOOM back to being great in 07
Brett Farve: Came back from retirement to play for the jets didn't do that great. People thought he was done to. Went to the vikings and that 1st year BOOM back to being great.
We once took a QB that lost his job because he got hurt like Alex Smith did the backup took the job over and did well and kept the job. His name was Trent Green. Trent lead an offense that was FUN to watch. Give that offense ANY defense at all and we are talking superbowl People didn't know what was going to happen with Green he had questions if he was going to be able to stay on the field to. IT CAN WORK Sorry but it's just way to early to begin bashing the move
