This isn't going to be the same type of QB competition we've had in past years. Smith is the starter going in and will be given starter's reps. Sing will give Smith every opportunity to remain the starter. I'd be really surprised if he pulled him haphazardly.
Having to look over your shoulder simply comes with the territory of being an NFL player. Look at Tomlinson. The guy's a gimme HOFer and was shown the door. It's a "what have you done for me lately" league and Smith needs to perform regardless of who's behind him on the depth chart. I liked Hill for his fight, but let's be honest, his physical skills were a limiting factor.
I don't understand why anyone would be upset with this move. We brought in a QB who is more similar to Smith than Hill is, so if he does enter a game (either because Smith flops or gets injured), we don't have to change the whole game plan. It was a sensible move.
As for the Niners not calling Hill, could it be that there were some formalities of the deal not yet completed? From an outside perspective, it does seem unprofessional not to give Hill a call, but then again we've only read that one account. For all we know the Niners have called him since. I hope so, because Hill deserves better than that.
