Pitino could pull a Tarkanian Fresno State-like turnaround and have Iona relevant very quickly if he can get some impact players, especially grad transfers.
They have a great trio of guards between Isaiah Washington, Asante Gist and Isaiah Ross so there's a good foundation there.
Pitino will make this team the #1 best team in the MAAC, as they might already have been even without his hire, but no way they will be a top-25 team like what Tarkanian was able to do at Fresno State. Back when Fresno State was in the "old" WAC, it was a solid mid-major conference with teams like Utah, BYU, New Mexico and San Diego State.
The MAAC is the MAAC. It's a low-D1 conference nowhere near the level of play of other mid-major leagues like the Southern, MAC, Sun Belt, let alone the WCC, Mountain West, MVC, etc.
A realistic possibility is that Iona becomes the standalone team in a weak conference, like Vermont in the America East or New Mexico State in the "new" WAC.
However, I love the MAAC and live only 45 minutes outside of New Rochelle. No doubt the Pitino hire piques my interest and will I definitely check out Iona home games next year and especially away games when they play Fairfield.
