As a 15-year old reading Street & Smith's pro football in late summer of '66 reading about the improvement of the Dallas Cowboy offense in '65. Statements that Dallas had Meredith roll out more as the key element is only partially true. Watching film of Dallas the second half of '65 (2-5 the first half) saw that Tom had the Dallas offense in a single back wing alignment much of the time.
Yes, Dandy Don did roll out, but much more important with Hayes's speed, and three other receivers quickly into their patterns. The Cowpokes go 5-2 and "earn" a Playoff bowl berth. Mel Renfro was moved to offense in '66 to further this alignment and with his speed and athletic ability no doubt he would have contributed. Injury allowed free agent Dan Reeves to get playing time; which he took advantage of especially as a receiver).
Using 16 games as an evaluation of Dandy Don
