Brady's had a bunch of nobodies as his receivers his entire career, with occasional exceptions of greatness such as Moss (for only three years), Gronk, Troy Brown, and Welker (who has only shined as a receiver with Brady as QB). He's made it work all the time with a revolving door of guys that were cut and signed off the wire and would probably be working at Planet Fitness if they had any other QB than Brady throwing to them.
Heck yeah, he's benefited from having the greatest coach ever; who wouldn't? But to have some of the guys he's had to throw to and still have the success he's had is NOT all on Belichek, not even close.
Your comment about Manning working in FAR less than perfect conditions his entire career is...well...puzzling. Manning benefited from playing most of his entire career in domes (Brady's stat's in domes are better than Mannings, BTW) and had consistent receivers, at least much more consistent than Brady,
along with one of the greatest receiving RBs ever, Marshal Faulk. And as far as "tantrums", ANYONE can get frustrated and riled up. Remember, Manning gave us the wonderful Manning Face. :)
Here's a nice comparison between Brady and Manning. Here's a summary if you don't want to read the whole thing (it
is long): Brady is Manning's statistical equal despite playing his entire career outdoors with inferior talent; Brady puts up more points and wins more consistently than any QB in history; Brady typically beats Manning head to head even with inferior teams; and Brady doesn't crap the bed every year in the playoffs.
