What do you think about Vince Carter and Tracy McGrady not making the all star team again?

Vince Carter is my favorite player and he is an 8-time all star and led the NBA in all star voting 4 times, and Tracey was always starting, Vince and TMAC used to be guaranteed all star starters or at least make the team but Tracey struggling with injuries he hasnt really been heard of the last couple years (not a fan of him btw) and Vince is still a great player but his explosiveness is gone and really hasnt been himself since2007 when he averaged 25pts a game. Are their careers on the decline? this is the 2nd straight year they missed being an all star
