Jabari Smith Jr., 19, and Alperen Sengun, 20, the Rockets’ youngest players, speak often about the weight room work they plan for the offseason. The Pelicans’ Jonas Valanciunas spent the two games in Houston showing why. “Jabari, especially, when he gets stronger, he’s going to be a problem, because he’s going to take all that contact and finish at the rim, or not get pushed off his spot,” Silas said. “The same thing for Alpi. He is lower body strong, but he can get stronger and better fit, and when he does that, he’s going to be a problem, as well. They’re going to get some grown man strength as we go here.
