Rib, I am only referring to his time with the Chiefs. He was traded for to bring competence to the QB position, and he was loathe to commit a turnover. It did not help to have few weapons. I remember in one playoff game, he was reduced to having to throw to AJ Jenkins.
It sure is telling how well a QB can look when he has the proper weapons and support, and how a QB can struggle like Kaep did when his O line was a sieve while only having cut third string FAs to throw to.
Alex did well, and he did it against the last SB champ. The Chiefs are now favorites to win the AFC West. However, I am not going to anoint him as the second coming after one game. Yes, he has improved, and Hill is the real deal, but I also remember the playoff game where he tried to run the hurry up offense while huddling up. That last NFCC Game he played in, he went 1 for 13 in third down conversions, and did not complete more than one pass to a WR. He had 2 opportunities to lead drives in the end to win the game, but kept on throwing short of the sticks. That is why they replaced him with Kaep, who did win that NFCC Game and propel the Niners into the SB.
I will wait until Alex wins a SB, before I will say that JH made a mistake. Kaep came within 5 yards of winning that SB, and one pass from returning, so he may have his detractors, but Kaep still achieved much. Alex needs to get to a SB first.
