I agree. As was already pointed out in this thread 'a first round draft pick' could mean Cole Strange, or it could mean Drake Maye. Just because a draft class is said to be weak doesn't mean you won't find a diamond in the rough. Just because a draft class is said to be strong doesn't mean you don't end up with a bust as your pick.
The only thing you do know for sure is you get five years of controlled salary, which IMO is a pretty valuable thing.
Whether AJB is worth more than that is, of course, something worthy of debate. Or at least it was, till the trade was called in to NFL HQ. Now AJB is a Patriot, so of course, LFG!
