Izzo is a great coach, but even he can't turn a sow's ear into a silk purse & that's what he'd have to do to get this Spartan club to make it to Houston. Not every MSU team Izzo coaches makes the Final Four, "just" 6 in his 15 seasons as coach there.
Izzo's teams lost either 12 or 13 games in each of five seasons in a span of six from 2002 through 2007, the one that they didn't lose 12 or 13 was their only F4 in that timeframe - if people back then were saying they'd make the F4 anyway even though they were losing a lot of games, they would've been wrong over and over again. Raymar Morgan was better than people give him credit for - right now MSU is really struggling to replace both his talent & toughness - he wasn't always consistent, but he still managed to start for four years and be among a select group of 5 players in MSU history to score 1,500+ points and have 700+ rebounds.
Even so, MSU's F4 run last year was mostly because they got dealt a good hand - they were one of only two teams since 1992 to be seeded #3 or below to make the Final Four without facing the #1 or #2 seed in their region - the only other team? Georgia Tech in 2004, who went out in the second round the year following an appearance in the NC game, and all they lost off their finalist team was Marvin Lewis (kind of similar to Chris Allen), Robert Brooks and Clarence Moore (Brooks and Moore combined to average less in pretty much all statistical categories than Raymar Morgan did last year), plus they added Anthony Morrow. I'd say MSU this year is similar to GT in '05.
