That's where intangibles really come into play for me. Out of all my searching and scraping, I found absolutely nothing on Bathgate other than he was a great scorer. I couldn't even confirm if he was really fast or not.
Have you watched his Legends video? Andy
smokes Gadsby on a breakaway. Yeah, Gadsby is getting old by that point and yes, he has to take a diagonal route to the puck carrier, but Bathgate's first couple of strides left the defenseman with zero chance to catch him. Keep in mind, also, that this was towards the end of Andy's prime.
Makarov was blazing fast, and he seemed to be respectable defensively (TDMM says Makarov was used on the PK a lot). Makarov is the kind of player who elevated his linemates to ridiculous heights because of how gifted he was offensively and what he did with those gifts. I don't think Bathgate really did that on quite the same level. Makarov basically created the K in the KLM line, as evidenced by his colossal failure when not playing with Makarov.
No, steroids created that player, who was actually quite good on his own merits during the period when he was shooting up with the East German women's swimming team. Many people considered him more dominant than Makarov in international competition during the 80's, if the truth be told. It would be an exaggeration to say that Sergei was carrying that line. As for Makarov's defensive play...I watched both he and his former center in San Jose quite a lot (lived in the Bay Area at the time), and I saw it in the center, but nothing in Makarov. Now, maybe it was the coaching or the scheme or whatever, but I watched a few good years of the guy, and he wasn't doing much in the way of backchecking.
Great player, but I can't agree that he's on Bathgate's (or Kharlamov's) level.
