Given how the HOF seems to more of a "Hall of Very Good" anyways, it wouldn't shock me if Horford is already knocking on the door.
Win a title or two as a key player and he's almost certainly in.
That’s my thought as well. If Mo Cheeks is in, a lot of really good but not quite great guys should make it. Horford certainly surpasses that standard.
See I disagree, for every good-but-not-great guy who makes the HOF, I feel like there's 5+ who don't. For every Mo Cheeks (4x All-Star, 5x All-D, 1x Champ), you have a Sidney Moncrief (5x All-Star, 5x All-NBA, 5x All-D, 2x DPOY), or Paul Westphal (5x All-Star, 4x All-NBA, 1x Champ), or Tim Hardaway (5x All-Star, 5x All-NBA), or a Michael Cooper (8x All-D, 1 DPOY, 5x Champ).
Just comparing Horford to some other PF/C not in the Hall, I don't think it looks good. And if he does get in, it's probably going to be many, many years down the road.
