How old are you? Do you have any pro fights? When will you make your debut, if not? Chances are at 5-0 you can make the top five American list. Good luck to you.
Brock is done. He never officially retired, but there's probably only a 10% he ever fights again. He lost the vision in one eye and has another lucrative career to turn to.
Ruiz is the only legit american contender and this fall he will win the heavyweight title for the third time to cement his legacy and hall of fame career.
What about Malik Scott? 30-0 undefeated but no names on his record. Beat some ok journeymen (Bostice, Shufford, McGroom... Sparred with Toney. Probably more a prospect than a top fighter yet.. McCall, Golota, old Holyfield, McCline, Brewster or Barrett are other fighters that could make the #5 spot
Malik is good.. However, he hasnt been active and he only has had one minor step up fight... Luckily he's still in his 20's, but at this point its time to put the peddle to the metal... But to his defense, he's been in school and just had a kid...
