Im a little shocked its more than dunlap but knowing theres probably some incentives hes unlikely to see (probowl for instance). I figure the deals closer to 2m/year. Assuming his first year is guaranteed and 1m of next year, so maybe 3ish?
I'd say 3-4 guaranteed at the max. He's slated to start at LT, that's still pretty low for a starting LT. Hopefully he delivers value.
