Walsh certainly has the frame for a 197, but I think it's best to try and get Soldano down to 174. He's got to want it though. Casale could become a ranked wrestler IMO. If he's dedicated and in the room with Labs then it's definitely doable.
Don't forget about Ford at 165. He has shown some good potential. He beat the same Ohio State kid as Barbosa. With that said, I'd put Blanchette 4th in line right now. I think we need Ford and Blanchette to beef up a bit over the summer for that 174 spot. I can see Chapman growing into 184 (and perhaps Walsh moving up his final two years).
Don't forget about Magro. We're probably going to have a lot of skilled guys in that 157-174 ranch. If we're able to land Bassett, then I have to think we'd ultimately land Miller too.
While I know they're trying their best, we need to land top heavyweight transfer and bluechip recruit at that spot. I think that will be the most important hole that needs to be filled. This team is going to be special over the next few years and we'll need an anchor for that last match in the duals.
