Do teams usually trade away their best players that often?
Depends. Teams don't like hiring or keeping players who have major external commitments. Anything that makes a player be perceived as 'difficult' tends to really hurt how much teams wish to work with them, having major external commitments certainly qualifies.
Sanders having commitments to teams in two different sports would have represented a significant complication when drawing up contracts; beyond that there's the personal investment (time, energy, etc) when both teams would prefer to have someone who's 100% there for them, not to mention the risk of injury. Playing some other sport professionally is a big gamble to consider when signing or keeping a player.
From another angle, a player who's always being traded constantly needs to learn to mesh with a whole new set of players and the new team's playing style. Being able to do that over and over again successfully is an argument in his favour, not against him.
It's incredibly rare for someone to play at a professional level in more than one sport. It's even more rare for someone to excel in both. One doesn't need to be 'the best player on their team' for it to be impressive, even maintaining a journeyman career in both would have been a major accomplishment.
