A QB can most certainly make a WR LOOK better...or bring out that WRs fullest potential. If that weren't true, then he'd play the same and perform the same with Flacco, Mallet, my mom...whoever. Sharper reads, accuracy, quicker thinking, audibling out of trouble, etc all play into a QBs performance and ultimately the WRs performance. This false narrative that a QB cant make those around him better is crap. It's a team game. As those around you play better, you play better.
