I'm not going to go back pages to see if this subect was discussed just because you told KBF to do so. I know already & I'll answer KBF's question with a bit of background detail for him, you & everyone else,
Jim Van Pelt signed with the Bombers out of the University of Michigan. In 1958, he made the team as a rookie backup qb & played defensive back while Ploen was the starter. Midway during the 58 season, Ploen suffered an injury & Van Pelt took over. He played so well that Ploen couldn't get his starting qb job back. So he moved to the defensive backfield & played very well there. So well, that he had one interception in 1958 & another 10 the following season for 104 yards in 1959. Ploen was named a CFL Western Conference All Star that season at DB even though he came back to play qb the rest of the way after Van Pelt's shoulder injury.
Van Pelt started the 1958 Grey Cup & Ploen subbed in for some plays as well. So they both played the position in that championship game with Van Pelt getting the majority of the snaps. Van Pelt was also the Bomber placekicker. He kicked two field goals & 4 converts that game in a 35-28 win over the Ti Cats.
In 1959, Van Pelt again was the starter but suffered a hand injury during the exhibition season. He had to wear a cast on his non throwing hand. Still, he didn't miss a snap. In late September of 59, Van Pelt suffered a separated shoulder which ended his season & unfortunately his career with the Bombers. He never played for us again. During the off season, in late 1959, Van Pelt was drafted into the US Air Force for a 3 year hitch. After suffering his separated shoulder, Ploen had taken over from Van Pelt & he never looked back as he became the starting qb for the Bombers until he retired after the 1967 season. In between, winning 2 more Grey Cup championships at qb & also a finalist in 1965.
Van Pelt completed his Air Force duties in late fall of 1962. He was a special guest of the Bombers at the Grey Cup in Toronto as they wined & dined he & his wife in order to convince them he should come back, They tried to get Van Pelt to sign a new contract for the 63 season with the Bombers but he turned down the offer to become a chartered accountant in Chicago where he lived until he passed away last year.
Who knows why he turned down the Bomber offer as ther CFL was paying as good or better than the NFL at the time. Van Pelt showed no interest to play in the upstart AFL which began in 1960. However, salaries were beginning to rise as the new league was competing with the NFL & CFL for players. The Canadian dollar was on par with the US dollar back in those days so there were no implications with the exchange rate for American players going back to the US in the off season. Perhaps Van Pelt felt that the team belonged to Ken Ploen now after being away 3 years. Maybe he felt that he had lost his edge. He certainly lost his desire to play as he was ready to move on to other things than football. Whatever the case, he never came back. He settled into private life in the Chicago area.
So KBF, Ploen never started 4 consecutive Grey Cups as a qb but he won 3 as a starter & played in 6 championships.
