The combination of the old #16 and #17 at Hazeltine was a hot button for years. A large tree made the downhill 16th play as "the world's only dogleg par 3," according to some of the pros at the 1970 U.S. Open. The 17th was an uphill dogleg right that required most players to hit a 4-iron off the tee. Dan Kelly loved #17, but his influence was not enough to keep the two holes from being blown up. Sixteen is now a great, scary par 4 along lake Hazletine, and 17 is a fairly standard par 3.
