I mean this with respect, but this outlook is pure overreaction and poorly thought out. The second kick you referenced was thanks to a botched snap that was the first strike against the eventual departure of a long snapper.
Unless you can find a Justin Tucker type kicker on the open market, cutting Catanzaro is not a good choice as there's no upgrade out there.
You have the right to complain about missing a chip shot 24 yard FG, but to call for his head as a response can only be explained by typical fan emotion.
I have some numbers to underline your take:
Statistically only Tucker & Gostowski are better than Catanzaro. Catanzaro an Hauschka are about the same.
Catanzaro: 86.7% longest 61 yards
Vinatieri: 84.6% longest 57 yards
Zurlein: 79.8% longest 61 yards
Tucker: 89.2% longest 61 yards (he is better not much but yes)
Bryant: 85.4% longest 62 yards
Lambo: 86.0% longest 54 yards
Janikowski: 80.0% longest 63 yards
Hauschka: 86.7% longest 58 yards (so about the same as Chandler)
Gostowski: 86.9% longest 57 yards
Dawson: 84.5% longest 56 yards
(Catanzaro would be at 86.9% if he made both missed kicks were he totally wasn't at fault)
So at the rest, please stop complaining about the Kicker, we have probably one of the better in the league and he is young, he probably is going to get better. There are maybe only one or two constantly better kicker in the league and drafting one high like TB doesn't help at all.
We have to fix the problems and that isn't the kicker. The Kick starts with the LS, the blocking, the holder and than the kicker has the chance to put it through.
Our team doesn't perform well in the first 3 phases of a kick and now fans that look at isolated outcomes without the whole picture, how it came to that outcome, are attacking a good kicker.
So please, stop this kind of nonsense threats, because Cat finds many takers on the open market.
