I think drafting Stafford would be the worst possible decision the Chiefs could make. Tell me, does this sound familiar?: "Born with a rocket launcher for a right arm... Puts too much zip on the football on intermediate and crossing routes ... Doesn't show an understanding to audible into the correct pass protection or diagnose coverages."

Read all the scouting reports you need, they all pretty much say the same thing. Lazer rocket arm, questionable decision maker. JaMarcus Russell anyone? Can you tell me that last time that a guy with a rocket arm drafted early turned out great?
Matt Ryan has a good arm, but makes really good decisions(thus far). The most glaring need/weakness for the Chiefs right now is a pass rush and linebackers. The secondary picked a ton of balls this year considering opposing passer had an eternity of time to throw the ball.
