In short: What current MLB streak/record will be the hardest for someone to break? Bleacher Report lists them in this order:
10: 73 homeruns in one season: Barry Bonds
9: .367 career batting average: Ty Cobb
8: 1,406 career stolen bases: Rickey Henderson
7: 2,632 consecutive games played: Cal Ripken, Jr.
6: 7 career no-hitters: Nolan Ryan
5: 4,256 career hits: Pete Rose
4: .426 average in one season: Napoleon Lajoie
3: 309 career triples: Sam Crawford
2: 56 game hitting streak: Joe DiMaggio
1: 511 career wins: Cy Young
Obviously, most if not all of those could be considered unreachable, but which one do you think has the lowest possible chance of being broken? I think I agree with Bleacher Report and Cy Young's 511 career wins.
