Worst course on Tour by far.
Slightly offline drives are massively penalized by the rough and prodigious length of the never-ending stream of par 4s on this tree-choked layout.
Birdie opportunities are practically non-existent unless you happen to hit a good wedge on one of the two unreachable par 5s.
And good luck with the par 3s if the greens are super firm (like they were in 2016, when Firestone played as by far the toughest Tour stop).
Firestone would be partially redeemable if recovery possibilities were more realistic and legitimate, but even then, the course would still be a bunch of long, straight par 4s with zero imagination or whimsy.
Hard pass.
