The absolutely correct answer is that it is made from meat that is suitable for roasting. The best thing to say, especially for roasted beef, is that cow meat cannot be roasted better. Either the calf will be a real calf, that is, it will not be old enough, or it will be a calf. It will also have a place suitable for roasting.
For example, you trusted a friend and shared the sacrifice of the calf. Your friend showed you his bull before the sacrifice and slaughtered his unproductive cow on the day of sacrifice. You have become complicit in this. Well, you can't make roasted beef from that meat. It can only be used as minced meat. Don't try in vain to make roasted food from it. Don't beat yourself up for nothing and don't get angry. Such things make people cold. What should we do, say we bought ground beef for the price of tenderloin and be upset with your fate. Mince them all. There is nothing to do about this situation.
Are you craving good roasting? Go to town, cut up about 1 kilo of entrecôte, cut it into cubes and roast it. Look how it's roasted like Turkish delight. The miracle is in the best meat, and that is the slightly fatty meat, from which the famous doctrine of roasting in its own fat derives. You really have to be a highly unskilled person to roast meat that is worse than good. No, I mean, put the meat in a pot, turn the heat on, stir, and it will cook on its own. If anyone can't do this, come and watch us, our kitchen is open, we cook it in front of everyone.
