Best case: Bosa lives up the hype and the odds and wins Defensive Rookie of the Year, becoming the team’s primary sack machine and taking over as its best overall defensive player.
He proves himself capable of being a three down player, succeeding as both a run stopper in base defense and a pass-rusher, racking up tackles and sacks for what proves to be a formidable defensive line for the 49ers.
Worst case: The No. 2 overall selection fails to fully get his feet under him, forcing him into a position where he only fits as a situational pass-rusher on obvious passing downs.
