The first is a complete lack of subtlety. Would a bar really be sponsored almost exclusively by Coors Light? The signs, napkin holders, napkins, light shade over the pool table, lack of other visible taps, etc. Would bar owners ever drink the same beer exclusively? Only if that beer were free, which doesn't happen. With the copious amount of beer choices, they'd mix it up. And the prevalence of other characters drinking it, just throws Coors Light in viewers' faces.

The second is a matter of choice. Coors Light seems like an odd one for these guys. I lived in Philly for nine years and am confident that people don't drink Coors Light bottles unless they're on a super cheap sale or special deal. Nobody drinks Coors Light bottles in Philly dive bars, especially not in South Philly where Paddy's is located. And worse, it's not really believable that any of the characters, save the vain Dennis, would be drinking Coors Light. Remember, this is the crew that drank inexpensive wine out of a Diet Coke can.

What They Should Be Drinking

Bars in South Philly can be roughly divided up into two categories: Hipster bars and locals bars. Hipsters have moved into pockets of South Philly and are usually found drinking PBR, other cans like Dale's Pale Ale, or microbrews, such as those from the semi-local Victory Brewing Company. Considering that Paddy's few customers are old guys, it's not a hipster bar.

It is a locals bar. Philly locals do drink cheap domestic beer, but not Coors Light bottles. Perennial favorites are Budweiser and Miller Lite. Budweiser is out because it's already got the Entourage product placement. Miller Lite is an option. But the best choice would Yuengling, a step up from the mass-produced Miller. Yuengling is from eastern Pennsylvania and has a semi-national footprint. It's the beer served at Philly-area college keg parties when trying to class it up from the usual Natural Light. Yuengling is so prevalent in the area that its flagship brand is simply referred to as "lager." For It's Always Sunny in Philadelphia, Yuengling would've fit in seamlessly.
