Brady didn't play great, but yes it would be foolish to insinuate that he choked in any way. With 3 superbowl rings and numerous game winning drives, his reputation as being "clutch" is set in stone...The Ravens just have a better team than the Pats, They had a better team then the Pats last year as well...The wild card was just how Flacco would perform, and he has showed up so far in the playoffs this year.
If anybody choked I would say Matty Ice did by clutching his shoulder like a wounded animal down the stretch of the biggest game of his career...but again, I think San Fran was the better team anyways, but Ryan had a golden opportunity to ice that game and couldn't do it .
I think the two best most complete teams made it to the Superbowl so It should be a fun game and enjoyable to watch...A perfect opportunity for Flacco to cement his legacy and prove he is really "elite"...he's beat arguably the two best QBs in the game on this run, so it would be a shame to loose to basically a rookie in Kap. But the Ravens have struggled against mobile QB's like RG3 so it will be interesting to see which team can play their best game when the lights are brightest !
That's the thing about people claiming others are clutch though. It's always colored by the narrative they want to give a small sample of games rather than what reality probably is. It makes a good story and that's why people want to see it that way. In reality good teams that are better than the competition win more often, but they also usually have a pretty good chance of loosing anyhow, and that is often not taken into account. Sometimes things happen and teams win or lose despite being better or worse than whom they play and it's nothing more than that. It's even worse when it's a situation where one game will send you home for the season. People often forget that random variance plays a big part in most sports, and it's that and the players normal skill and talent more than magical pixie dust that makes people play better that makes the outcomes of them. The two best most complete teams were probably the Broncos and the Patriots this year, but like I said, in a series of only one game the better teams less times than not but still often lose. it's just the nature of the game and most sports. I think if you could set up a situation where somehow the Broncos or Patriots could play the Ravens ten times with pretty much all things at the start of their last games being equal the Broncos would win about 8 of them and the Patriots would have won 6 or 7.
About Flacco, unless Flacco can put up at least multiple seasons as one of the few of the greatest QBs in the game, he's not elite. Doing aright in a couple of games doesn't make one elite. (The same also goes for why Eli isn't elite.) If he's ever a top 5 QB for 3, 4, or 5 or more years then I might consider him that. At this point he's not even close and probably will never be. Throughout his career he's been lucky to be considered average so far.
