I respectfully disagree with your post. First of all, Sinden was a HOF caliber coach, based on his championship in OKC and SC with Boston in 1970. His coaching of Team Canada in 1972 was also stellar. As a new GM in 72, he quickly rebuilt the team after the expansion draft and WHA loses, bringing the team back to the SCF in 74. He also made some great trades, cashing in on players he thought were in the early stages of decline, such as Esposito and Pederson. His drafting record wasn't good at all and he let a number of valuable players leave for free.
ER did INDEED win the #1 goalie job in training camp the year he was drafted, so wasn't a bust out of the gate, but his sitting for six months, playing in zero games Pejorative Slured his development. Perhaps he was a flash in the pan like Moffatt, but we'll never know. Your statement that he wasn't a bad draft pick initially and that he was a stiff isn't true.
