Loov is our replacement when Polak is moved i believe. The reason he was called up was because in the discussion that management and Keefe have before every call-up. keefe recommended Loov.
He is a steady decenseman now and likely going to make the leafs next year out of camp. If he is not traded. At present he is a excellent mix of mobility and toughness and very very solid defensively.
I wouldn't mind him not getting sent back down. His offensive game is conservative and he is not one to take risky chances. He just plays a safe game. I would not be surprised to see his offense get much stronger over the next 2 to 3 years.
