5. His Rookie Year- Borland finished his rookie season with 108 tackles, 1 sack, and 2 interceptions in only starting 8 games for the Niners. he was also the first rookie linebacker in franchise history to get two interceptions in one game and was selected as the NFL's Defensive Rookie of the Month for November. Not bad for a rookie. 4. Stastics Shows He's Not The Only One- According to the NFL Players Association the average career length is about 3.3 years. 3. 2014 San Francisco 49ers season- 18 49ers including Borland himself, were sidelined with injuries.. 2. Chronic Traumatic Encephalopathy (CTE)- a neurological disorder found in professional athletes who have experienced repetitive brain trauma. A  brain injury study conducted at the Boston University School of Medicine showed that 33 of 34 players tested post-mortem showed clear signs of CTE, including recently HOF inductee Junior Seau, who tragically committed suicide with a gunshot wound to the chest in 2012. Borland even cited his concern of head trauma for his reason of early retirement. 1. The NFL​- the game was getting dangerous over the years with Helmet-to-helmet collisions and/ore low blows, making Borland's reason for retirement more legitimate than one.
