Marcus dictates position and keeps it towards his strengths. One can't argue with the results. And I do not find Marcus's matches to be boring. For old-timers, my comp would be Lee Kemp. Lee got a hard time about not scoring more points when he probably could have. But Lee's matches were artistic masterpieces. Even with a close score, rarely was Lee under a serious threat of losing.
I get the coach's point to a degree. He may be suggesting that Marcus may not fully develop if he simply relies on his currently dominant positions. But when wrestling for a spot on an Olympic or world team, the goal is to win and advance -- not develop. By securing his spot on those teams, Marcus will get to train with the best. I am sure he is working on developing new skills and more dominant positions within that training. I think he trains regularly at the Ohio RTC with Logan, Jags, Nic B., Jesse, et al. The live goes and spars are probably much more experimental than Macus's elimination tournament wrestling matches. Just my two cents.
Somebody on Flo speculated that Marcus has not yet committed because he won't be going to OSU and does not want to burn his ORTC training bridge too soon by committing elsewhere. I don't buy that for several reasons. Mainly, Marcus has out-developed the other super stars of his era (Luke, Jax, Bo Bassett, etc.) due in part to his training environment. Why would he not want to stay on that course? I don't think Kyle Snyder has improved since he went to PSU (even though his reason for going was for his wife's career more than his own, which is truly admirable and wise given that she is a doctor). Second, I don't think Logan, Coleman, et al. would throw Marcus out. For one, their wrestlers gain by training with Marcus. And also, with the transfer portal, etc., they would not want to burn a bridge with Marcus or the Burnetts..
