My very superficial reading of the salary cap FAQ indicates that any rookie with full bird rights (which they have here) can be extended to pretty lucrative contracts. The 120% of average salary/current salary is for veterans only (which makes sense, of course).They should be able to offer enough he bites. Think it’s like 4/60m+ they can offer. If not he’s restricted so they are fine.
And in that case, yes, I guess he might very well take it, but in any case he's going to add quite significantly to their 24-25 luxury tax.
