Froling has been playing national team ball for 4 years now, according to his FIBA stats page. Avg 12.9 ppg, 9 rbds during that time in 5 Int'l tourneys. Could he give us good minutes? Yes.
However, wIth Martin & Jacob both playing the 5 there won't be many available minutes left. Probably the best we can hope for is spot minutes along with PT in blowout games in the non conference portion of the season.
