Just so you remember your claim is Bree's lack of playoff success on the road was due to him being limited in physical size, which correlated to him struggling in away games in the playoffs due to bad weather (you will try and spin it to something else after this anyway).
Sherlock? He actually does research. You sound like the snarky little know it all who saw a segment about Drew Bree's on ESPN, that claimed his lack of playoff road success was due to weather and now claim it as your own knowledge. Now lets just see if your little theory is actually based on any facts about Bree's road playoff games.
Game 1: Jan 11, 2007 GTW- 20 deg 10 mph wind. Bree's 27/49 354yrds 2TD 1INT.
Probably the worst playoff weather conditions Brees ever faced, as a 3pm kickoff in Chicago it got cold and the wind actually picked up some. Had to be Brees inability to throw in the cold and wind that lost this game right? Not the fact that he was on his first ever road playoff game against the #3 ranked D in the NFL. 354 yards and 2 TDS is just crap, the running game was stellar with 56 yards 0TDS and 2 Fumbles lost. Chicago in January just to much for little Drew.
Game 2: Jan 8, 2011 GTW- 40 deg 8 mph. Brees 39/60 404 2TDs
In this game it was the 8mph wind that caused Bree's to allow Seattle to score 41 points
Game 3: Jan 14, 2012 GTW-62 deg 2 mph wind. Brees 40/63 462yrds 4tds 2ints
Brees wet the bed on this one by throwing 2ints against the #2 ranked D, if it wouldn't have been so windy (with that tiny little arm) it would have been 0 ints.
Game 4: Jan 11, 2014 GTW 48 degs 20mph wind. Brees 24/43 309yrds 1TD
First time ever in a playoff loss Brees failed to throw over 350 yards (309) and multiple TDs (1). Clearly this abysmal performance was because the 20+ mph winds (it was actually really windy), I mean Wilson with his cannon for an arm threw all over for 103 yards on 9/18 passing. If Brees was strong enough to throw in the wind it was an easy win. One of the D best pass defenses in modern NFL history really didn't play a factor at all.
Game 5: Was in a Dome (Minnesota) no weather factor.
So as you can clearly see by the weather and by the numbers Brees put up in the 4 road losses, his lack of size and arm strength was why he only won 1 SB. It is clear that 5 SBs was a shoe in if he had a big strong arm.
Now go and try and spin it. Maybe you can go cherry pick some regular season games where the weather was bad and he didn't have a great game.
