1. You already have a good qb: Jason Campbell is a good qb with lots of talent! he has a the kinda arm you want out of an NFL QB and he is mobile. He gets better every year and he does it with multiple coordinators and it's not like he has a great offensive line and this year he had probably the best year of his career with no running game! Also speaking as a brotha can we please stop getting rid of the black QB's please! (example: Aaron Brooks, Shaun King, Dante Culpepper).
2. Bradford is injury prone: Sam Bradford is ranked #1 on Mel Kipers Quarterback draft board. Why? he hurt his throwing arm twice! Do I have to repeat it again? he didn't just hurt his shoulder he hurt his THROWING ARM TWICE! But Mel Kiper still seems to think that Bradford is still the best QB in the draft and he just like many others think the Redskins should take him with the forth pick in the draft but with an offensive line like the Redskins he will not last long if you think about it!
3. You don't know what you are getting out of Bradford: We've seen what Campbell can do but not Bradford. So how do we know he's not the next Ryan Leaf he is no guarantee in the NFL and who knows how Bradford plays after that injury because for all we know it could have just made him slower and you need to be quick when you step on an NFL field.
