They get down multiple scores and he cannot stretch a field.
like versus Buffalo where they came back? yeah.
Alex is a better version of Trent Dilfer. KC has almost all the pieces you need...strong running game, good line, good defense, good kicking/special teams. they have a top notch TE. their WR corps.....eh. and they dont make mistakes. Alex is not going to Brady you with a 30/40 330 and 3 TD....but he wont Kaepernick you either with 10/27 120 3 INT. he's mobile (5ypc i think???) and wont kill your team with bad passes (see Romo, Tony). I am not a big fan of the coaching staff, but the head coach has been to super bowls so......
not to mention other teams are really running into injury issues.....KC lost their best player earlier this season but their backups have been good.
they arent the best team in the AFC but they are top 6 and they are trending upwards and healthy.
