Because Farragut finally figured out they had to play zone and has the size and enough quickness to match up. They played them even the last 3 quarters of the second game and finally realized they could play with them. Farragut beat Science Hill in the beginning of the year (before they got "coached up") and gave Walker Valley their only loss so they were a pretty good balanced team when their bigs weren't in constant foul trouble.
It's all about matchups. Is there a Memphis team that has enough size to match up with Simpson, Parker, Craig, and has superior quickness? Plus what are the odds that Blevins will have another melt down like last years DB sectional loss? In the Farragut game Bearden was definitely better when they played the big 5 more.
