You're reading things into the situation that aren't there. There's nothing unusual about a non-arbitration RFA still being unsigned on August 12th. The deadline to get a deal done is the first day of training camp, and that's a soft deadline.
If I'm his agent, I'm waiting as long as I can to see what Shane Pinto and Morgan Frost get so I can use that as leverage to get more for my client. The Rangers have some flexibility and his agent knows that. We have $2,278,417 in cap space with a 22 man roster. If we send down Belzile and Mackey, that number jumps up to $3,828,417. So even if we give Laf 3 mil per year, that's still 800k in cap space with a 21 man roster.
If you were Laf's agent, wouldn't you be trying everything you could to get him more money?
