Not only would keeping Doueihi for depth a good decision, it'd likely come cheap.
If there's not much first grade interest for us around, which I doubt there would be, Doueihi in position 20 - 30 in a roster is excellent. With an average top 30 contract being nearly 400k, having him on anything from 250-350, on a season by season basis, provided he's happy to do so, is a no-brainer in my eyes.
To have Adam Doueihi as no 3/4 on halves depth, no 4/5 on centre depth, etc, on a small-medium contract in the back end of your Top 30 is good business.
We need an upgrade from Adam at left centre, it may be May, it may not be May, but I'd rather keep Adam in the squad than the likes of Tumeth, Matamua, Feledy, Faataape, Saukuru, et al.
