I played high school basketball seriously. OK, we did not have a great team, but I played and scored 8-10 points a game at a high school of 3,000. Our hoops practices were serious, and at times strenuous. Running helped because of the fitness. In the games where we met teams from the city with lots of quality height, we played zone (out of necessity), and I finished games feeling hardly fatigued. (Man to man against a great city guard left me very tired, though).
I also ran seriously in high school, running a 4:08 mile my senior year.
There was no comparison really, between the stress of basketball practice and the stress of xc and track practice. XC and track practice just took a lot more out of me. Basketball practice was intense, but there were breaks, and running sprints, defensive drills was more or less about brute force effort. It was far harder to learn how to relax and concentrate with the intensity levels required of running.
Division 1 XC and track were much, much more difficult than my high school basketball work-outs. I never could compare them personally to Division 1 basketball workouts, because, well, my school is a consistent Div. 1 powerhouse, and I couldn't dream of playing hoops there. My basketball player friends did indicate an intensity level greater than high school practice (these days, the proliferation of AAU ball means very few learn how to really put the effort in on defense at the high school level), but I nevertheless intuit that XC and track workouts are, like my high school experience, more stressful than in basketball.
Another set of anecdotes, and it likely varies by individual: Basketball, like track, made me often very sore and tired. I recovered more quickly from a tough basketball practice than a tough track practice, though, and this was likely due to the breaks which occur with even the toughest practices. The sorest I remember being, though, was after a workout or tough race (or races) on indoor board tracks. I suspect I did not work hard enough on running light on my feet, but board tracks just beat the heck out of me and made me very sore, worse than anything in basketball.
I think this CSU basketball coach should not be taken seriously, as he likely has little experience with both sports. It does make his guys feel "tougher" though, and given mindset of a typical college basketball player, it soothes some egos.
My father was a state champion high school coach in both track and XC in a big state, and was an excellent basketball coach, having played Division 1 basketball. He thought track practices were more stressful (kids did not really learn from basketball practices longer than 90 minutes, at least he thought), although the level of talent he had for track likely surpassed his basketball team talent, and he may have had more flexibility to work the runners harder.
