They have rolling totals and how much a team is covering by during the game on their scoreboard.

Well there is what's called a 'dutching' calculator. If you google it, you input all the odds and the amount of money you want to wager. Then it spits out how much you should put on each one, to give you an even profit across the board. If you wanted to do Lamelo seperate, then don't include him in the calculations. E.g. if you have $5000 to play with, and you know you want to put $2000 on Lamelo, you will put your bankroll as $3000 (the remainder) on the dutching calculator, and it will split that $3k across the remaining bets.
