Which was what, his 1st or 2nd year with a clear defined role and an opportunity to play more than 1 or 2 games before being dropped? I can see where you are coming from but I think a two year deal isn't too much to ask, the clause would work too I suppose.
A one year contract offer doesn't have to mean the club only wants him around for one more year. Tucky played out the end of his career on one year contracts quite happily. If Knights gets back to fitness next season Whitey may have some stiff competition for his spot! Would match a two year offer if that was a sticking point for him, but would start with a one year deal
