Right now, I am reading a preview of the book about the Montana and Steve Young rivalry called Best of Rivals.
In 1986, SF columnist Glenn Dickey suggested the day after Montana's surgery (he missed eight games that year after getting hurt in Week 1) that the 49ers trade for Steve Young.
Young wasn't available because Steve DeBerg was hurt. However, what if he was healthy, and the 49ers were able to trade for Young that September? And, what if Young goes undefeated while Montana was out? Do they even bring back Montana that year?
And, if Young plays well in the playoffs (I think they may do better than 10-6, but they still lose at the Giants in the divisional round), what becomes of Montana in 1987?
