This being repeated does not make it true. Long's actually struggled run blocking way more often this year then he has in previous years. At least, according to PFF
CP does make a fair point in Bush dancing more than last year, and I blame that on the zone blocking scheme not having the right fits. Last year Long and Cog were VG in getting a push and Bush followed their lead with VG results. This year, they are moving more sideways, and Bush is waiting for an opening, which is not happening.
