Wayne County Executive Warren Evans said on Monday the offer requires "much deeper analysis" that could push a decision on the deal into May.
He wants to analyze the proposed deal and whether it could meet Wayne County's needs for a new adult and juvenile detention facilities, a new criminal courthouse and sheriff's and prosecutor's offices
“This offer needs greater review, and it’s going to take time and effort and resources,” Evans said. "There are many questions that need to be answered."
Besides the 23,000-seat soccer stadium, the downtown site would include office, commercial, hotel and residential space and parking.
The MLS bid was submitted by Detroit Pistons owner Tom Gores and Gilbert.
