"Tough a** yards" is definitely correct, and Gore has had his challenges. After being named Big East Freshman Of The Year by Sporting News when attending the University of Miami, he tore his left ACL during spring practice. After rehabbing, he tore his right ACL the next season. He was known as one of the Three Amigos, a RB trio that included Gore, Clinton Portis and Willis McGahee, both of which who were drafted much higher than him albeit in different years. Portis was a 2nd round pick in 2002 and McGahee was a 1st round pick in 2003.
Gore was drafted in the 3rd round as the 65th overall pick by the 49ers surrounded by skepticism that his injuries would hold him back in the NFL. It was that criticism that drove him to work harder. In the post game presser he actually said, "I wanted to prove everybody wrong." The always humble Gore also took the time to say, "It's a blessing. Thanks to the organization and thanks to the O Line. It's special."
Gore who is 31, has had a new role this past off season: as mentor to rookie RB Carlos Hyde who is likely to transition as the feature back. They have a similar downhill running style. Hyde who had his first NFL touchdown vs. Dallas, was met by a jubilant Gore on the sidelines. Don't retire Gore just yet though, he's as powerful as ever between the tackles.
