Totally agree with all of this, spot on. Cottee on his day was a good player and he did score 20+ goals for us in at least one season. But he was your archetypical goal hanger, he lived on tap ins from a few yards out. He very rarely created anything himself. He wasn't the type of striker who could win you a league title on his own, and the style of football he needed to score wasn't conducive to him forming a striker partnership with anyone either. Kendall dropped him frequently in the early 1990s due to his form.
Another thing you touched on that I meant to mention earlier was the cliques within the club - the players who'd won the title (the likes of Sharp, Southall, Watson, Sheedy all still there) and the new people Harvey and then Kendall brought in, the likes of Keown, Beagrie etc, who were nowhere near the class of the former group of players. There was the infamous fight between Sheedy and Keown at the Chinese restaurant in Southport, which pointed to a pisspoor team spirit, and then there was the time in the pre-season tour of Spain in 1991 when Beagrie got pissed after a match with Real Sociedad, got lost and couldn't find the team hotel, and rode someone's motorbike through a plate glass hotel entrance window (at the WRONG HOTEL I should add) and needed 50 stitches. Somewhat humorous looking back but at the same time pointed at a club in disarray behind the scenes.
