Coffeys numbers at best-on-best tournaments are very impressive and especially his performance at the 1984 Canada Cup really stands out. However while his knockout stage numbers are strong he clearly did most of his scoring at the group stage (21 pts in 18 gp).
While Chelios obviously does not match up with Coffey offensively I would say that he still possibly may have the most impressive best-on-best resume of these players thanks to his 3 very impressive tournaments in 1991, 1996 and 2002 where he was voted to the tournament all-star team every time. I don't think that Chelios performance at any of those tournaments was quite as impressive as Coffeys performance in 1984 though and all in all I would probably say that Chelios and Coffey are on roughly the same level when it comes to best-on-best performances.
Park had a strong performance at the 1972 Summit Series. The same can not be said about Dryden though since he overall clearly had some struggles during that series. I do think that Dryden playing all of his best-on-best games against a highpowered offensive team with a very different playing style than he was used to can help explain his struggles to a certain degree. Still as evident by his other performances against Soviet teams in the 75/76 Super Series game and the 1979 Challenge Cup it is not as if Dryden managed to adjust that well to their playing style later on either (though he was at least alright in the Challenge Cup).
If we look at the whole group of available players when it comes to best-on-best resumes I would say that the ones that belong to the top group are Chelios, Coffey and Bossy. Behind them I would have Park. Then Yzerman and Robinson in some order and then I would say that Dryden has the weakest best-on-best resume in this group.
