Simply put:
When Martz did the get good WRs and pass a bunch approach:
The Rams went to the playoffs in 1999, 2000, 2001, 2003, 2004 (5 times in 6 years)
When McVay did the get good WRs and pass a bunch approach playoffs 2017
That makes 6 times in 7 years.
Years that they got prodders at WRs and did not pass a bunch.
1990,1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016,
21 times and 0 playoffs.
So, what do you do, go with the 6 out of 7 approach or go with the 0 out of 21 times approach.
While Watkins disappointed some, the Rams need either him or somebody of his caliber and the Rams need to continue to pass all over the field and continue to create space for Gurley to run, by passing often and everywhere. Make the defense defend every inch of the field and every player on the field.
