I tried to find some other comparable contracts at capgeek.com. Not alot that are real good comparables...
Ladislav Smid (23), 2 yrs, $1.3M cap hit
Roman Polak (23), 2 yrs, $1.1M cap hit
Matt Hunwick (24), 2 yrs, $1.45 cap hit
Shaone Morrisonn (26) 1 yr, $1.975M cap hit
I also agree Grossman could be one of the guys to get a longer deal (4 or 5 years), especially if he plays well this season.
At a minimum I would expect he would get about 2 years and $1.9M cap hit. If he goes to arbitration, he should hit $1.75M easily for one year.
A 4 year deal (1.8, 2.2, 2.8, 3.2) around $2.5M cap hit or 5 year at close to a $3M cap hit wouldn't surprise me either. I think Grossman has a great season and the Stars look to lock him up longer term.
