Perhaps not this specific case but, unless I can be linked to somewhere that says otherwise, I do think offer sheets are more common than we may ever know because theyre rarely signed
I could also be very wrong - which is why id be interested to read on it from a former executive's view one day
Could be a level of play in the background with offer sheets that we dont know; for example, besides contention between teams, why wouldnt every organization that can afford to make reasonable attempts thatll likely be matched? You never know when one day a team just says f*** it for some reason or another and you get yourself a good player
Teams could kick the tires. Montreal approached Brayden Point who declined as he was happy in Tampa. Montreal then pivoted to Sebastian Aho who was willing to sign since negotiations with Carolina weren't going well. Back when the Devils were in salary cap purgatory in the summer of 2006, I think Brian Gionta mentioned that a couple teams approached him but he didn't consider it.
And then there's the case when Mitch Marner was RFA and allegedly Columbus would have been willing to sign him. Seemed like Marner's camp was never particularly interested in Columbus but was happy to leverage a hypothetical offer sheet as part of the negotiation with Toronto.
But realistically there's what, five teams that would have the draft picks and cap space for Byfield? And how many of those are situations that Byfield would entertain?
Overpaying for an average guy like Spence/Kaliyev could have repercussions down the line. I've wondered if Martin Necas has felt slighted since he's been a better player than Jesperi Kotkaniemi, but he's been paid less due to those offer sheet shenaningans.
And why not just work out a boring trade if it came down to it?
Also my favorite cautionary tale about offer sheets was Tampa in the summer of 2008. They wanted a young D to grow with Steven Stamkos and they decided they would offer sheet Andrej Meszaros since Ottawa had cap problems. Unfortunately Tampa didn't have the foresight to not trade one of the required 3rd rounders and were unsuccessful in getting it back. After it dragged into late August, they eventually worked out a trade and sent Filip Kuba and a different 1st rounder to Ottawa who sadly thought their window was still open.
If Tampa had done the offer sheet as originally intended, they would have forked over their own 2009 1st rounder aka the Victor Hedman pick.
