Not according to Tebow supporters. Unfortunately I suspect that regardless of whether Sam is a total bust who gets cut early or a breakout talent who is a starter from day one, it's going to be blamed on or credited to his sexual orientation.
Unconditional Tebow supporters aren't really football fans. He won a couple of games including a great playoff win against the Steelers, but a third of his yards were on one play and post-season he still had the lowest passing % in the entire league.
Winning one playoff game doesn't mean you're a franchise QB. Hell Trent Dilfer won 11 straight games after coming off the bench, including the Super Bowl and he was STILL cut at the end of the season.
Tebow could have continued in the NFL if he hadn't insisted on being a QB (probably would've made a great TE).
The idea that he was cut because he was a Christian is just ridiculous, and something that's only said by non-NFL fans who've never heard of Kurt Warner.
