Is that really a concern Shane? Tabs would start in the 50, with Hogan playing more of a true CHF role, but they would switch depending on match-ups. If you thought we could play three talls, you could add Cox, or send him down back.
I reckon having Hogan would add another 10 or 20 goals a season to Tabs season tally. I wouldn't be surprised if over the course of a season Hogan was the more valuable player, but Tabs kicked more goals.
Given Tabs hasn't made double figure games the last couple of years, having another tall option couldn't hurt.
