Honestly, I'm in the same boat. I guess, by using deductive reasoning, the team wouldn't be willing to give him more than the 2nd round tender price of $2.75m.
I'd probably low-ball him with maybe a $1.5m base salary, $250k signing bonus and maybe $31,250k per game active roster bonus (as injury safeguarding). Max value if he's healthy is $2.25m for the season.
